WebMay 5, 2015 · The Anti-de Sitter/Conformal Field Theory correspondence (AdS/CFT), however, is a new type of duality which relates a quantum field theory on flat spacetime to a string theory. This is particularly remarkable since string theory is a very promising candidate for a consistent theory of quantum gravity. Naively, quantum field theory on flat ...

WebOct 19, 2024 · In anti-de Sitter space a highly accelerating observer perceives a Rindler horizon. The two Rindler wedges in AdS d+1 are holographically dual to an entangled conformal field theory that lives on two boundaries with geometry ℝ × H d−1.For AdS 3, the holographic duality is especially tractable, allowing quantum-gravitational aspects of … In theoretical physics, the anti-de Sitter/conformal field theory correspondence, sometimes called Maldacena duality or gauge/gravity duality, is a conjectured relationship between two kinds of physical theories. On one side are anti-de Sitter spaces (AdS) which are used in theories of quantum gravity, … See more Quantum gravity and strings Current understanding of gravity is based on Albert Einstein's general theory of relativity.
