Comparing Candidate Theories of Quantum Gravity

[Bertin]

Hi, you all,

I have been for a couple of semesters interested in quantum gravity as a problem, but truth is I never have been properly introduced to any of the candidate theories. Actually, there are multiple candidates and I would like to compare them. The question then is the following: do you know of any monograph or small set of articles I can read to get a impression of the main ideas and "philosophy" behind each of the most common theories, in order for me to find the one that pleases me more? Despite how useful it is for other things, I really don't like using Wikipedia in this case.

Thank you in advance!

Is this book "approach independent"? Why do you recommend it?

Carlip wrote an overview,

It's a bit outdated, but I guess it still can be useful.

This is a wonderful book, but it is not about theories of quantum gravity, it is about Hawking radiation and related effects, e.g., in expanding spacetimes. Standard QFT is about quantum fields in the a fixed spacetime that is Minkowski spacetime. This book is about quantum fields in other fixed (non-quantized) spacetimes. In my opinion this book is the best short, pedagogical introduction to Hawking radiation and related effects.

This book deals with several approaches

There are plenty of other useful references in the wiki article.

Ok, thank you very much. I'll look further into the references there, sorry for not having checked better!
