In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...
The Ryu–Takayanagi conjecture is a conjecture within holography that posits a quantitative relationship between the entanglement entropy of a conformal field theory and the geometry of an associated anti-de Sitter spacetime. [1][2] The formula characterizes "holographic screens" in the bulk; that is, it specifies which regions of the bulk ...
The entropy of entanglement is the Von Neumann entropy of the reduced density matrix for any of the subsystems. If it is non-zero, it indicates the two subsystems are entangled. More mathematically; if a state describing two subsystems A and B is a separable state, then the reduced density matrix is a pure state.
In 1974, Hawking predicted that black holes might not be the bottomless pits we imagine them to be -- and now, ... Entanglement is a quantum connection of sorts between particles. Entangled ...
Black hole information paradox. The first image (silhouette or shadow) of a black hole, taken of the supermassive black hole in M87 with the Event Horizon Telescope, released in April 2019. The black hole information paradox[1] is a paradox that appears when the predictions of quantum mechanics and general relativity are combined.
Entropic gravity, also known as emergent gravity, is a theory in modern physics that describes gravity as an entropic force —a force with macro-scale homogeneity but which is subject to quantum-level disorder—and not a fundamental interaction. The theory, based on string theory, black hole physics, and quantum information theory, describes ...
Hawking radiation is the theoretical emission released outside a black hole 's event horizon. This is counterintuitive because once ordinary electromagnetic radiation is inside the event horizon, it cannot escape. It is named after the physicist Stephen Hawking, who developed a theoretical argument for its existence in 1974. [1]
In that research, they calculated the entropy from quantum entanglement in conformal field theory via the Bekenstein-Hawking entropy of black holes in the context of Juan Maldacena's holographic principle and conformal field theories on a surface correspond to a theory of gravity in the enclosed volume.
