Frontiers in Physics, 2021 The investigation of quantum–classical correspondence may lead to gaining a deeper understanding of the classical limit of quantum theory. I have developed a quantum formalism on the basis of a linear invariant theorem, which gives an exact quantum ...

Classical-quantum correspondence for fields [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 We map the quantum problem of a free bosonic field in a space-time dependent background into a classical problem. $N$ degrees of freedom of a real field in the quantum theory are mapped into $2N^2$ classical simple harmonic oscillators with specific initial conditions.

Correspondence between classical and quantum resonances
Physical Review E, 2021 Bifurcations take place in molecular Hamiltonian nonlinear systems as the excitation energy increases, leading to the appearance of different classical resonances. In this paper, we study the quantum manifestations of these classical resonances in the isomerizing system CN-Li⇆Li-CN. By using a correlation diagram of eigenenergies versus Planck constant,

Higher rank quantum-classical correspondence
Analysis & PDE, 2023 For a compact Riemannian locally symmetric space $Γ\backslash G/K$ of arbitrary rank we determine the location of certain Ruelle-Taylor resonances for the Weyl chamber action. We provide a Weyl-lower bound on an appropriate counting function for the Ruelle-Taylor resonances and establish a spectral gap which is uniform in $Γ$ if $G/K$ is irreducible of

JIMWLK evolution, Lindblad equation and quantum-classical correspondence
Journal of High Energy Physics, 2020 In the Color Glass Condensate (CGC) effective theory, the physics of valence gluons with large longitudinal momentum is reflected in the distribution of color charges in the transverse plane.

Inflationary quantum dynamics and backreaction using a classical-quantum correspondence
European Physical Journal C: Particles and Fields, 2021 We study inflationary dynamics using a recently introduced classical-quantum correspondence for investigating the backreaction of a quantum mechanical degree of freedom to a classical background. Using specifically a coupled Einstein–Klein–Gordon system,

Pozůstalost archeologa Wilhelma Kleina v Archivu UK
Acta Universitatis Carolinae: Historia Universitatis Carolinae Pragensis, 2023 This contribution presents the collections of Classical archaeologist Wilhelm Klein (1850–1924), kept in the Archive of the Charles University, which have recently become accessible to researchers. Klein worked at the German Charles–Ferdinand University (

Quantum-Classical Correspondence in Response Theory [PDF]
Physical Review Letters, 2005 The correspondence principle between the quantum commutator [A, B] and the classical Poisson brackets iota h{A, B} is examined in the context of response theory. The classical response function is obtained as the leading term of the expansion of the phase space representation of the response function in terms of Weyl-Wigner transformations and is shown

Classical-quantum correspondence and Hawking radiation [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 A recently discovered classical-quantum correspondence (CQC) maps certain quantum problems to corresponding classical problems. We illustrate the CQC for a quantum scalar field in the gravitational background of a collapsing spherical shell. By truncating the problem to a small set of variables, we show how the CQC can yield Hawking radiation as well ...
