Loop quantum gravity - Wikipedia
Loop quantum gravity (LQG) is a theory of quantum gravity that incorporates matter of the Standard Model into the framework established for the intrinsic quantum gravity case.
Loop quantum gravity: Does space-time come in tiny chunks?
2022年2月23日 · Einstein's theory of general relativity tells us that the warping of space and time is what we experience as the force of gravity. Quantum mechanics tells us that what we experience...
What is Loop Quantum Gravity? - Universe Today
2010年1月14日 · The two best theories we have, today, in physics – the Standard Model and General Relativity – are mutually incompatible; loop quantum gravity (LQG) is one of the best proposals for combining...
[2104.04394] A Short Review of Loop Quantum Gravity - arXiv.org
2021年4月9日 · Abstract: An outstanding open issue in our quest for physics beyond Einstein is the unification of general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading approach toward this goal.
I present here a short introduction, for non-specialists, to some basic concepts of Loop Quantum Gravity – a non-perturbative canonical quantization of General Relativity. ∗Speaker.
History of loop quantum gravity - Wikipedia
Loop quantum gravity (LQG) thus became related to topological quantum field theory and group representation theory. In 1994, Rovelli and Smolin showed that the quantum operators of the theory associated to area and volume have a discrete spectrum. [11]
Loop quantum gravity: beginnings-In 1986 Ashtekar shows that one can write canonical gravity with variables similar to those in Yang-Mills theory. -General relativity looks like an SU(2) Yang-Mills theory with extra constraints.-Opened hopes that techniques used to quantize YM could be applied to gravity.
Quantum Loop Gravity | Insights, Challenges & Theory
2024年5月27日 · Quantum Loop Gravity (QLG) stands as one of the most promising and intriguing theories in the realm of theoretical physics. This theory aims to bridge the gap between two pillars of modern physics: General Relativity, which describes the macroscopic world, and Quantum Mechanics, which explains the microscopic phenomena.
Loop Quantum Gravity | Living Reviews in Relativity - Springer
A problem that has been repeatedly tied to quantum gravity, and which loop quantum gravity is able to address, is the problem of the ultraviolet infinities in quantum field theory. The very peculiar nonperturbative short-scale structure of loop quantum gravity introduces a physical cutoff.
Exploring Quantum Loop Theory: An In-Depth Analysis
Quantum loop theory presents a compelling framework for reconciling the realms of quantum mechanics and general relativity. In this rapidly evolving field of theoretical physics, it serves as a cornerstone for our understanding of the universe's structure at the smallest scales.
