A Wigner Quasiprobability Distribution of Work
Entropy, 2023 In this article, we introduce a quasiprobability distribution of work that is based on the Wigner function. This proposal rests on the idea that the work conducted on an isolated system can be coherently measured by coupling the system to a quantum ...

Covariant chiral kinetic equation in non-Abelian gauge field from “covariant gradient expansion”
Journal of High Energy Physics, 2021 We derive the chiral kinetic equation in 8 dimensional phase space in non- Abelian SU(N) gauge field within the Wigner function formalism. By using the “covariant gradient expansion”, we disentangle the Wigner equations in four-vector space up to the ...

Entropy, 2020 The quantum effect on the Wigner time-delay and distribution for the polarization scattering in a semiclassical dense plasma is explored. The partial wave analysis is applied for a partially ionized dense plasma to derive the phase shift for the ...

Results in Physics, 2023 The Wigner quasi-probability distribution function is an important tool for estimating the quantumness of quantum states. The Wigner distribution function (WDF) is related monotonically to the coherent field state density operator and their probability ...

Wigner distribution function of volume holograms [PDF]
Optics Letters, 2009 Based on a linear systems approach, we derive the Wigner distribution function (WDF) of a 4f imager with a volume holographic three-dimensional pupil; then we obtain the WDF of the volume hologram itself by using the shearing properties of the WDF. Two common configurations, plane and spherical wave reference volume holograms, are examined in detail ...

EURASIP Journal on Advances in Signal Processing, 2021 Linear canonical transform (LCT) is a powerful tool for improving the detection accuracy of the conventional Wigner distribution (WD). However, the LCT free parameters embedded increase computational complexity.

Quantum nature of Wigner function for inflationary tensor perturbations
Journal of High Energy Physics, 2020 We study the Wigner function for the inflationary tensor perturbation defined in the real phase space. We compute explicitly the Wigner function including the contributions from the cubic self-interaction Hamiltonian of tensor perturbations.

Dynamical entropic measure of nonclassicality of phase-dependent family of Schrödinger cat states
Scientific Reports, 2023 The phase-space approach based on the Wigner distribution function is used to study the quantum dynamics of the three families of the Schrödinger cat states identified as the even, odd, and Yurke–Stoler states.
