Books on LQG

Each of the five parts is supplemented by a section on ‘Questions and Answers’, where authors and editor ask questions to other authors after having read their contributions. These sections are indeed very helpful, and it occurred more than once that I myself had a question which I found answered there. A person who is already well versed in quantum gravity research might even wish to read these sections by themselves in order to get an impression on the various existing opinions in this field. —Claus Kiefer

This book presents an unconventional ten-year “long-exposure photograph” of the evolving field of quantum gravity. In this field, there is potential for breakthroughs in interlinking diverse approaches, many of which are covered in this book. [...] It is suitable for students, researchers and anyone interested in learning what practitioners of quantum gravity consider as the critical obstacles to understanding quantum spacetime.  —Astrid Eichhorn

This is an excellent introduction to spinfoams, an area of loop quantum gravity that draws ideas from Regge calculus, topological field theory and group field theory. It fills an important gap in the literature offering both a pedagogical overview and a platform for further developments in a forefront area of research that is advancing rapidly. —Abhay Ashtekar

[...] A First Course in Loop Quantum Gravity is the first book on this topic that is accessible already to undergraduates. No previous knowledge of general relativity and quantum field theory is required; instead, the necessary material from these subjects is introduced in a clear and pedagogical way. The authors present the key features of loop quantum gravity, but also do not hide its weak points. The book can be recommended to anyone from student to established scientist [...].  —Claus Kiefer
