[HTML][HTML] Recent advances in Wigner function approaches
J Weinbub, DK Ferry - Applied Physics Reviews, 2018 - pubs.aip.org
The Wigner function was formulated in 1932 by Eugene Paul Wigner, at a time when
quantum mechanics was in its infancy. In doing so, he brought phase space representations …

Effective drifts in dynamical systems with multiplicative noise: a review of recent progress
G Volpe, J Wehr - Reports on Progress in Physics, 2016 - iopscience.iop.org
Noisy dynamical models are employed to describe a wide range of phenomena. Since exact
modeling of these phenomena requires access to their microscopic dynamics, whose time …

Time averaging and emerging nonergodicity upon resetting of fractional Brownian motion and heterogeneous diffusion processes
How different are the results of constant-rate resetting of anomalous-diffusion processes in
terms of their ensemble-averaged versus time-averaged mean-squared displacements …

Anomalous diffusion and nonergodicity for heterogeneous diffusion processes with fractional Gaussian noise
Heterogeneous diffusion processes (HDPs) feature a space-dependent diffusivity of the form
D (x)= D 0| x| α. Such processes yield anomalous diffusion and weak ergodicity breaking …

[HTML][HTML] Bose polaron as an instance of quantum Brownian motion
We study the dynamics of a quantum impurity immersed in a Bose-Einstein condensate as
an open quantum system in the framework of the quantum Brownian motion model. We …

Real-time methods for spectral functions
In this paper we develop and compare different real-time methods to calculate spectral
functions. These include classical-statistical simulations, the Gaussian state approximation …

Entangling two macroscopic mechanical resonators at high temperature
At high temperature, thermal decoherence dominates so that the entanglement of quantum
states is difficult to preserve. Realizing high-temperature entanglement is, therefore, a …

Coherence and information dynamics of a -type three-level atom interacting with a damped cavity field
An analytical description of a three-level atom in an optical cavity coupled to the
environment is obtained. The Husimi function and the Wehrl density are calculated to …

Strong-coupling quantum thermodynamics of quantum Brownian motion based on the exact solution of its reduced density matrix
CZ Yao, WM Zhang - Physical Review B, 2024 - APS
We derive the quantum thermodynamics of quantum Brownian motion from the exact
solution of its reduced density matrix. We start from the total equilibrium thermal state …
