Quantum Gravity 2025​

​

The latest installment of the biennial Quantum Gravity conference organized under the auspices of the International Society for Quantum Gravity (ISQG) took place at the Pennsylvania State University’s Eric J. Barron Innovation Hub July 21-25, 2025, in a hybrid in-person/virtual format. The conference brought together around 100 researchers from many different approaches to the problem of quantizing gravity, who together contributed over 70 talks and posters.

Presentations included perspectives from string theory, loop quantum gravity, causal sets, asymptotic safety, and causal dynamical triangulations. Physical questions concerning quantum gravity effects in cosmology and black holes were explored within effective field theory and semiclassical and discrete approximations. Presenters also shared ideas and developments from work on quantum foundations, modified gravity, quantum gravity phenomenology, and analog gravity. 

The plenary sessions included recent research overview talks, a presentation by a PRD editor, and several topical discussions. Those were followed by themed sessions of contributed talks in the afternoon. Despite the challenging funding and travel environment in the US, the organizers put together an interesting scientific program that was well attended and led to lively Q&A after the talks and engaging exchange of ideas during the dedicated discussion sessions. All talks and discussion sessions were recorded with links to the talks to be available soon on the conference site.

Lee's Fest: Quantum Gravity and the Nature of Time

 

On June 6th, Lee Smolin turned 70. This created the occasion for a meeting of ideas, creativity, and friendship. On the first week of June, Perimeter Institute hosted a conference honoring one of its funding members, whose vision shaped the institute since its beginnings 25 years ago. The conference was filled with fond memories of those early years of the institute, as well as from before. The earliest memories were shared by Herb Bernstein, Lee’s teacher at Hampshire College, where much of the inspiration for an engaged and creative way of learning come from.

Many participants brought recollections of seminal scientific ideas at the origin of Loop Quantum Gravity. On the first day, Carlo Rovelli reviewed the results in his joint papers with Lee: the loop representation, the computation of the discrete spectra for area and volume, and the first definition of the Hamiltonian evolution. He weaved the recollection of those results with an inspiring tale of a great scientific and human friendship. More presentations, then, composed a shining mosaic of those  early loopy days. From Ted Jacobson, that together with Lee found the first solutions of the Wheeler-deWitt equations using loops, to Abhay Ashtekar, mentioning the “3-man paper” at the foundation of Loop Quantum Gravity. From Viqar Husain, the first student of Lee in Yale, to Madhavan Varadarajan, who was later the first student of Lee in Syracuse. And to Seth Major, also graduate student of Lee, with whom he pioneered the use of quantum groups in LQG. All the way to some of the latest students of Lee in PI, such as LinQing Cheng, today working at the intersection between quantum gravity and quantum information. All together they painted a beautiful arc, bridging from the beginning of quantum gravity to the research going on today. More contributions on loops and beyond included those by Bianca Dittrich, Laurent Freidel, Etera Livine, Simone Speziale, and myself - mentioning the spinnetwork evolution studied by Lee and Fotini Markopoulou seminal for the development of spinfoams.

The conference reflected the large diversity of research directions that Lee has explored, in particular in quantum foundations, cosmology, and philosophy. The many different contributions highlighted how Lee’s work has reached diverse fields, always keeping as distinctive trait the combination of technical skills and an uncompromising intellectual courage. An example of this is his idea of applying natural selection in cosmology, brilliantly merging ideas and tools from biology into the evolution of the universe. Or his attempt to use gauge theory to understand the financial market. The list can be long! Indeed, the most astonishing trait emerging from all the tributes paid to Lee during the conference is the diversity of directions from which Lee has taken inspiration. Including, very importantly, art.

Therefore, a celebrations of Lee’s science needed to be also a celebration of his interactions with artists: the conference hosted a visual art exhibition, a jazz concert, a debate about the creative connubium of art and science, a piece of music composed for Lee, the reading of a poem dedicated to him… and even a movie world premiere! I think such special atmosphere enabled some of the speakers to give their best to convey their scientific message in a way effective and unconventional as ever (kudos to Fay Dawker’s theatrical performance, just to highlight one).

Sharing this week with Lee, and listening and participating to the unusually ample discussions during the conference, has been for many a heartwarming experience. Many stories repeatedly highlighted Lee’s generosity, especially when it come to support younger researcher. Those who benefited from past interactions with Lee, by sharing their stories, have certainly inspired the younger participants and presented an example of the kind of scientist and human being to which we can look up. Even if you were not there, not all inspiration have been lost: most of the conference has been recorded and videos can be found at https://pirsa.org/c25023.

FAU² Workshop: Quantum Gravity Across Scales

​​

The "FAU² Workshop on quantum gravity across scales: from physics at the Planck scale to effective theories" was held from May 20–22, 2025, at the ECAP (Erlangen Center for Astroparticle Physics) Laboratory in Erlangen, Germany. The event gathered over 30 participants in person and 20 more online, creating a vibrant environment for discussions on the interplay between quantum gravity approaches at the Planck scale and their corresponding low-energy effective descriptions. It brought together experts in canonical and covariant loop quantum gravity (LQG), group field theory (GFT), string theory and asymptotically safe gravity, fostering dialogue across different frameworks.This was the third workshop jointly organized by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Florida Atlantic University (FAU). The workshop format prioritized collaboration: mornings were reserved for informal discussions and joint work, while afternoons featured structured talks and thematic sessions. This year's program included contributed talks and a poster session, offering early-career researchers a platform to present their work

The workshop was organized into six thematic sessions, covering both foundational aspects of quantum gravity and applied topics, including cosmology, black hole physics, and relational/quantum reference frames. Some highlights were the role of effective theories accessed via the renormalization group, effective models of quantum cosmology and LQG-inspired phenomenological models, black hole physics and collapse scenarios in the context of asymptotic safety and LQG-inspired effective models, foundational questions about holography, group field theory, effective spin foams, quantum reference frames and dressed observables, the algebra of observables and quantum field theory, and recent results on perturbation theory in black hole spacetimes. Each session was complemented by contributed presentations, whose work enriched the discussions and brought fresh perspectives on all covered topics. For further details please visit the website of the workshop.The day’s talks concluded with discussion sessions focused on the session's themes. These discussions were particularly fruitful in clarifying semantic ambiguities, especially around the notion of “effective” across different approaches. Participants shared challenges, explored opportunities for cross-framework connections, and debated possible challenges and future steps for quantum gravity approaches in the context of black holes and cosmology.

​

Social events, including a welcome reception and a barbecue dinner, extended the scientific conversations in a relaxed atmosphere, that, among other options, also included Bavarian beer and traditional sausages.

Report on the DPG Spring meeting 

The DPG Spring Meeting of the German Physical Society (DPG) took place from 31 March to 4 April 2025 in Göttingen. The German Physical Society is divided into several sections, and the conference in Göttingen was the one that covered the Matter and Cosmos section, which includes particle physics, gravitation and relativity, and mathematical physics, among other things. 

​

As part of the celebrations marking the 100th anniversary of quantum mechanics, the speakers from GR and Mathematical Physics sections, Luciano Rezzolla and Johanna Erdmenger, organised a joint symposium on the current status of quantum mechanics and gravity. The symposium was dedicated to presenting the current state of research on quantum gravity. It brought together the perspectives of four speakers,  Nils Obers, Kristina Giesel, Renate Loll and Alessia Platania, working on different approaches to quantum gravity, namely string theory, loop quantum gravity, dynamic triangulations and asymptotic safety. Denmark – the home of quantum physicist Nils Bohr – was the guest country at the DPG Spring Meeting in Göttingen and the organisers were particularly pleased to have two speakers from Denmark in the symposium

​

The session was well-attended and there were lively discussions after the talks. There were several parallel sessions in particle physics, GR and Mathematical Physics, covering various topics in these fields. They usually began with a longer invited talk, followed by shorter talks, with many younger researchers presenting their work in the latter.

Bad Honnef Physics School on Searching Quantum Gravity in the Sky

In the 3rd week of February of 2025, the German Physical Society (DPG) Bad Honnef Physics school on Searching quantum gravity in the sky. was organized at the Physikzentrum in Bad Honnef under the BridgeQG COST action. The 5-day long school, that was attended by roughly 70 masters and PhD students from all over the world, included experimental as well as theoretical lectures on quantum gravity phenomenology, with the central subject being Lorentz invariance violation (LIV) and its experimental observations in high-energy astrophysics.


The school was kickstarted by an introductory talk by Christian Pfeiffer (ZARM Bremen), one of the main organisersof the school together with Giulia Gubitosi (U Napoli), Tomislav Terzić (U Rijeka) and Jose Manuel Carmona (U Zaragoza). The theoretical lecture was given by Giacomo Rosati wherein he touched upon two phenomenological approaches that aim at modifying special relativity, viz., LIV and doubly special relativity (DSR). The experimental lectures covered the different aspects and complexities involved in observing potential LIV through astrophysical sources. These were given by Jelena Striškovič, Rafael Alves Batista and CaterinaTrimarelli wherein the hunt for LIV observations via time-delays in high-energy gamma-ray photons and via interaction threshold reactions, as well as the experimental challenges in the detection of cosmic messengers, were discussed in detail.

Apart from these main topics of the school, there were two additional talks covering potential deviations between theory and observations. The first of these was given by Jackson Levi Said wherein the current tensions in cosmological observations were discussed. The second of the these, which concluded the school was given by Flaminia Giacomini wherein she discussed theoretical notions in low-energy quantum gravity and introduced some thought-experiments aiming at identifying quantum gravity effects.
During the school, all attendees had the opportunity to visit the Effelsberg 100-m Radio Telescope, gaining hands-on experience with one of the world's largest fully steerable radio telescopes. Participants learned about its working principles and operational procedures, adding a practical dimension to their understanding of observational techniques relevant to quantum gravity phenomenology.
The Bad Honnef Physics Center, with its castle-like architecture, comfortable accommodations, and excellent dining facilities, provided an ideal setting for immersive learning. The residential format encouraged continuous scientific exchange among students and lecturers, strengthening the sense of community in the field. There were also numerous social activities, including shared meals, a poster session, and a karaoke night, which further fostered interactions among participants. The school was co-funded by the BridgeQG COST action, which aims to bridge the gap between low- and high-energy quantum gravity research initiatives and foster further interaction. In alignment with this objective, the next edition of the school is planned for 2026 , with a focus on low-energy quantum gravity.

12th Tux Winter Workshop on Quantum Gravity

Around 40 researchers from the field of quantum gravity from Europe, Asia and North America met for five days in Tux in the Austrian Alps, at the 12th Tux winter workshop on Quantum Gravity Feb 10 to 14, 2025. The goal of this workshop series is to report and discuss new results and ideas at the conference venue, but also during hikes, on the ski slopes, or over dinner in the restaurants of the little mountain resort.

In October 2024, Jerzy Lewandowski, founder and co-organizer of the workshop series had passed away and so this year's edition was held in his memory and had a special focus on his work and research interests. In both, invited and contributed talks, many references to Jerzy Lewandowski were made to his kind and generous personality and his fine humor as well as to his towering scientific achievements.

The invited speakers Abhay Ashtekar, Fernando Barbero, Bianca Dittrich, Kristina Giesel, Wojciech Kaminski, YonggeMa, Guillermo Mena Marugán, José Mourão, Daniele Oriti, Jorge Pullin, and Thomas Thiemann reflected on Lewandowski's work and his personal and scientific influence on them. They also presented their own recent work, some of which was directly related to earlier results by Jerzy Lewandowski.

​

Invited and contributed talks reported on progress in understanding a wide range of topcis, from classical and quantum black holes, apparent horizons, quantum cosmology, precanonical quantization, effective actions, entanglement in quantum field theory, asymptotic charges and covariant phase space, to higher gauge theory, among others. A public talk by Jorge Pullin on gravitational waves recounted, in a highly entertaining way, the circuitous history of the subject, from Newton's first ideas to their eventual detection and the 2017 Nobel prize in physics.

​

Over a workshop dinner, participants had had the chance of catching up and hatching plans for the future. For those participants that did not have to leave quickly after the end of the official program, the workshop ended with a dinner at mountain hut and a nightly snowy sled ride down to the village under the starry sky.

The next edition of the workshop series will take place Feb 9 to 13, 2026. More Information will follow in due time.

JUGAR II workshop
on quantum gravity, qft in curved backgrounds, gravitational waves and cosmology

The JUGAR II Workshop was held in Madrid from December 3 to 5, 2024. JUGAR means “to play” in Spanish, and stands for “Journey through the Universe. Gravitation and Advanced Relativity”. The name of the workshop reflects its broad scope, ranging from inflation to gravitational wave detectors, and covering different aspects of quantum field theory in curved backgrounds, semiclassical gravity, and quantum gravity.

The workshop served as the closing event of the joint grant The Quantum Gravitational Universe, in which four Spanish nodes from different institutions in Madrid and Granada participated. A year and a half ago, the first JUGAR Workshop was held to exchange ideas and results generated during the implementation of the grant. On this second occasion, the main organizers were Gianluca Calcagni and I, both from IEM-CSIC in Madrid. As I mentioned above, the event aimed to bring together leading experts in Advanced General Relativity, including quantum-related topics. In the workshop, applications to symmetry-reduced models, cosmology, black holes, gravitational radiation and related areas were discussed. Loop quantum gravity played a prominent role, with talks by Kristina Giesel, Thiago Guedes, Mercedes Martín-Benito, Javier Olmedo, Daniele Oriti, Thomas Thiemann, Francesca Vidotto, and myself. Most importantly, there were also a good number of oral contributions from students of the Spanish groups, showing the wonderful activity that the new generations are developing in the field. In total, we had more than 40 registered participants. The scientific environment was very enriching and relaxed, with a dynamic and interactive touch that helped us meet the tight schedule. The good weather in Madrid and the beautiful CSIC campus in the heart of the city undoubtedly contributed to completing a magnificent setting for the workshop. Let’s hope that, if we want to play again with important questions in gravitational physics, there can be more workshops in the JUGAR series to continue enjoying our research.
