Loop Quantum Gravity Resources

In summary, Marcus has created a resource page for loop quantum gravity. He has also listed books, papers, and online tutorials that should be helpful for those interested in learning more about this subject.

I think it will be. I especially like that so much is available free online. Much of the online stuff (and hardcopy as well) has appeared just in the past year. It's definitely a useful list. We should keep it updated as more resources become available.

Impressed with the large section that is just about cosmology (LQC) an important application that is how a lot of people come to LQG these days.

Thanks.. This is also a good list.. In your list i only know rovelli,gambini,carlip,thaiman . But i did not know the others. Thanks for listing those..:cool:

Superstring, you might find this useful
http://indico.cern.ch/getFile.py/access?contribId=30&resId=0&materialId=slides&confId=21917

It is the slides for the talk that Carlo Rovelli gave at Cern this week (21 August) to the String 2008 conference. It is a broad accessible introductory talk about Loop and Spinfoam QG, for non-specialists. Introductory because presumably most string theorists do not know much about current developments in loop and related areas. So it might be useful for other people besides that particular audience. See what you think.

Thanks marcus! sorry for late reply. It should really be helpful for all non-specialists including me. I will check it..:biggrin:

I just saw it and could not wait to thank you again. Wow! great job by rovelli.

that link was to the pdf file of the slides for his talk. there is also a video of the talk itself.
One can watch and listen to the talk, while scrolling down thru the slides (the video does not always show the projection of the slides clearly, so the pdf can give better resolution.)

Rovelli said he was pleased with the interest shown and getting so many questions from the audience---said they asked good questions and also more numerous compared with typical responses to other talks.

I should get the link to the video. Let's try this:
http://cdsweb.cern.ch/record/1121957?ln=en
Yes! this is it. And at the end there are questions, when the camera turns around and takes in the audience. I was impressed by how much interest, the hall is packed. Even some people standing up because not enough seats. The tone of the many questions is courteous interest, Carlo's responses relaxed and frank. It was so successful that I would expect a repeat of this general sort of opening up, in the next conference Strings 2009 which will be in Rome. Perhaps they will invite Rovelli again, or it could be someone else, like Renate Loll or Abhay Ashtekar. I think it is very much to the credit of the organizers at CERN that they invited a speaker from nonstring quantum gravity to open up their theory universe a little. Hopeful development.

Sorry wrong expression. I wanted to say.. i just looked at that file.. Thanks for the new link

Here is the direct link for the video

That is a nice site. I checked out several topics that branch off from the homepage:
http://cosmicposts.wordpress.com/

It is handsomely designed, with effective graphics and color images.
And careful: work went into listing selected resources.
And clearly organized.

Thanks Marcus. I wanted to be regular to write this blog. But don't get much time! Thinking to start writing again.

For your website to serve as a resource for people, you don't need to be posting on it regularly---only as needed to keep the list up to date (of the best LQG resources).
I hardly need to point this out! It's obvious that the essential thing to make it useful is ensuring that other people know it is there. For that, you don't need to be posting constantly. You need only visit other places and leave the link.

I will put it in our LQG list of resources here at Beyond forum. If nobody needs it, fine. But if they do need it they have a chance to find it. For the right person your lists could be quite helpful.

I put it here:

You never knows what comes about from such simple networking. Maybe nothing. Maybe something. Studies must come first. Internet activity is a distant second. But thanks.

Thanks for your advise. I will try to update it regularly.
 

1. What is Loop Quantum Gravity (LQG)?

Loop Quantum Gravity is a theoretical framework in physics that aims to reconcile general relativity and quantum mechanics. It proposes that space and time are quantized at the smallest scales, and interactions are described by loops or networks.

2. How does LQG differ from other theories of quantum gravity?

LQG differs from other theories of quantum gravity, like string theory, in that it does not require extra dimensions or fundamental particles. It is also background-independent, meaning it does not rely on a fixed spacetime background.

3. What are some resources for learning about LQG?

There are many resources available for learning about LQG, including textbooks, research papers, and online lectures. Some popular books include "Loop Quantum Gravity: The First 30 Years" by Abhay Ashtekar and "Quantum Gravity" by Carlo Rovelli. Online resources include the Perimeter Institute's online course on LQG and the International Loop Quantum Gravity Seminar.

4. Is there any experimental evidence for LQG?

Currently, there is no experimental evidence for LQG. However, researchers are working on ways to test its predictions, such as through measurements of gravitational waves or the cosmic microwave background radiation.

5. What are some current challenges in LQG research?

Some of the main challenges in LQG research include finding a way to incorporate matter into the theory, addressing the issue of time in a background-independent framework, and resolving the issue of non-renormalizability. There is also ongoing debate and exploration around the role of spin networks and spin foam models in LQG.
