Hace 4 días · The quantum theory of gravitation, effective field theories and strings: Past and present. by Clare Sansom, SciencePOD. Credit: CC0 Public Domain. Gravity is one of four fundamental interactions ...
Hace 4 días · Attempts to quantize gravity require an understanding of Planck-scale phenomena, a domain explored by string theories [31–34] and loop quantum gravity [35–38]. These theories, alongside others like noncommutative field the-ory [39–41], massive gravity [42,43], f(T) gravity [44– 55], and Horava-Lifshitz gravity [56], incorporate the
Hace 2 días · 20 Despite several excellent contributions to gravity theory, among which Krugman (Citation 1980), Bergstrand (Citation 1985, Citation 1989, Citation 1990), and Deardorff (Citation 1998), the gravity model was just considered an example of “social physics” and some of the theoretical rationale had been disregarded in most of the empirical literature until the early 2000s (Yotov Citation ...
Hace 4 días · It is an attempt to develop a quantum theory of gravity based directly on Albert Einstein's geometric formulation rather than the treatment of gravity as a mysterious mechanism (force). As a theory, LQG postulates that the structure of space and time is composed of finite loops woven into an extremely fine fabric or network.
Hace 7 horas · General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation ...
Hace 2 días · Another popular theory is loop quantum gravity (LQG), which describes quantum properties of gravity and is thus a theory of quantum spacetime. LQG is an attempt to merge and adapt standard quantum mechanics and standard general relativity. This theory describes space as an extremely fine fabric "woven" of finite loops called spin ...
Hace 5 días · The workshop’s topics will include (i) optical and condensed matter platforms for quantum computing; (ii) quantum simulation of problems of interest for condensed matter, nuclear, high-energy, or gravitational physics; and (iii) hybrid quantum algorithms for optimization problems.
