QUANTUM-CLASSICAL CORRESPONDENCE IN THE ORACLE MODEL OF COMPUTATION [PDF]

International Journal of Quantum Information, 2006
The oracle model of computation is believed to allow a rigorous proof of quantum over classical computational superiority. Since quantum and classical oracles are essentially different, a correspondence principle is commonly implicitly used as a platform for comparison of oracle complexity. Here, we question the grounds on which this correspondence is

The Classical Origin of Spin: Vectors Versus Bivectors

Axioms
There are two ways of linearizing the Klein–Gordon equation: Dirac’s choice, which introduces a matter–antimatter pair, and a second approach using a bivector, which Dirac did not consider.

Renormalized holographic entanglement entropy in Lovelock gravity

Journal of High Energy Physics, 2021
We study the renormalization of Entanglement Entropy in holographic CFTs dual to Lovelock gravity. It is known that the holographic EE in Lovelock gravity is given by the Jacobson-Myers (JM) functional.

Classical limit of large N gauge theories with conformal symmetry

Journal of High Energy Physics, 2020
In this paper we study classical limit of conformal field theories realized by large N gauge theories using the generalized coherent states. For generic large N gauge theories with conformal symmetry, we show that the classical limit of t hem is ...

Brane dynamics from the first law of entanglement

Journal of High Energy Physics, 2020
In this note, we study the first law of entanglement in a boundary conformal field theory (BCFT) dual to warped AdS cut off by a brane. Exploiting the symmetry of boundary-centered half-balls in the BCFT, and using Wald’s covariant phase space formalism ...

Quantum-“classical” correspondence in a nonadiabatic transition system [PDF]

Physical Review E, 2004
A nonadiabatic-transition system which exhibits ``quantum chaotic'' behavior [Phys. Rev. E {\bf 63}, 066221 (2001)] is investigated from quasi-classical aspects. Since such a system does not have a naive classical limit, we take the mapping approach by Stock and Thoss [Phys. Rev. Lett.

The Fine-Structure Constant in the Bivector Standard Model

Axioms
The geometrical view of the electron as a spinning bivector leads to the partitioning of the electron’s energy into internal and external. The reduced Compton wavelength, λ¯C, is taken as the radius of the inertial ring (a disc), while re characterizes ...

The Zitterbewegung in the Bivector Standard Model

Axioms
We show that the Zitterbewegung of the electron arises as a real internal motion when spin is treated as a classical bivector rather than as a point fermion of the Dirac equation.

Holographic scattering requires a connected entanglement wedge

Journal of High Energy Physics, 2020
In AdS/CFT, there can exist local 2-to-2 bulk scattering processes even when local scattering is not possible on the boundary; these have previously been studied in con- nection with boundary correlation functions.

The spacetime geometry of fixed-area states in gravitational systems

Journal of High Energy Physics, 2022
The concept of fixed-area states has proven useful for recent studies of quantum gravity, especially in connection with gravitational holography. We explore the Lorentz-signature spacetime geometry intrinsic to such fixed-area states in this paper.
