The discussion revolves around the topic of second quantization in the context of Ashtekar variables and their application in quantum gravity, particularly in relation to loop quantum gravity (LQG). Participants explore the theoretical framework and seek resources or clarifications on the subject.
Participants express differing views on the classification of loop quantum gravity, with some asserting it is a first quantization theory while others argue it is a quantum field theory. The discussion remains unresolved regarding the nature of LQG and its relation to second quantization.
There are limitations in the discussion regarding the definitions of first and second quantization, as well as the assumptions underlying the classification of LQG. These aspects remain unresolved.
what i can understand is that lqg is a first quantization theory, isn't it?Demystifier said:Are you familiar with loop quantum gravity? If not, this is probably what you should search instead.
No, it is a quantum field theory. However, this method of quantization does not contain a notion of gravitons, so you may say that this quantum field theory cannot be viewed as a second quantization of gravitons, but only as a first quantization of gravitational fields.luxxio said:what i can understand is that lqg is a first quantization theory, isn't it?
