Scattering induced dynamical entanglement and the quantum-classical correspondence [PDF]

, 2006
The generation of entanglement produced by a local potential interaction in a bipartite system is investigated. The degree of entanglement is contrasted with the underlying classical dynamics for a Rydberg molecule (a charged particle colliding on a ...

Flat entanglement spectra in fixed-area states of quantum gravity

Journal of High Energy Physics, 2019
We use the Einstein-Hilbert gravitational path integral to investigate gravita- tional entanglement at leading order O(1/G). We argue that semiclassical states prepared by a Euclidean path integral have the property that projecting them onto a subspace ...

Integrable crosscaps in classical sigma models

Journal of High Energy Physics, 2023
We study the integrable boundaries and crosscaps of classical sigma models. We show that there exists a classical analog of the integrability condition and KT-relation of the boundary and crosscap states of quantum spin chains.

Correspondence in Quasiperiodic and Chaotic Maps: Quantization via the von Neumann Equation

, 1993
A generalized approach to the quantization of a large class of maps on a torus, i.e. quantization via the von Neumann Equation, is described and a number of issues related to the quantization of model systems are discussed.

Superselection sectors of gravitational subregions

Journal of High Energy Physics, 2019
Motivated by the problem of defining the entanglement entropy of the graviton, we study the division of the phase space of general relativity across subregions.

A New Look at the Arcsine Law and "Quantum-Classical Correspondence"

, 2012
We prove that the Arcsine law as the time-averaged distribution for classical harmonic oscillators emerges from the distributions for quantum harmonic oscillators in terms of noncommutative algebraic probability. This is nothing but a simple and rigorous

Algebraic description of spacetime foam [PDF]

, 2001
A mathematical formalism for treating spacetime topology as a quantum observable is provided. We describe spacetime foam entirely in algebraic terms.

Non-KAM classical chaos topology for electrons in superlattice minibands determines the inter-well quantum transition rates

Scientific Reports
We investigate the quantum-classical correspondence for a particle tunnelling through a periodic superlattice structure with an applied bias voltage and an additional tilted harmonic oscillator potential.

Einstein-AdS action, renormalized volume/area and holographic Rényi entropies

Journal of High Energy Physics, 2018
We exhibit the equivalence between the renormalized volume of asymptotically anti-de Sitter (AAdS) Einstein manifolds in four and six dimensions, and their renormalized Euclidean bulk gravity actions.

Hybrid classical-quantum dynamics

, 2000
A hybrid formalism is proposed for interacting classical and quantum sytems. This formalism is mathematically consistent and reduces to standard classical and quantum mechanics in the case of no interaction.
