We investigate quantum corrections to the classical work characteristic function (CF) as a semiclassical approximation to the full quantum work CF. In addition to explicitly establishing the quantum-classical correspondence of the Feynman-Kac formula, we find that these quantum corrections must be in even powers of ℏ. Exact formulas of the lowest corrections (ℏ^{2}) are proposed, and their physical origins are clarified. We calculate the work CFs for a forced harmonic oscillator and a forced… Expand
Quantum corrections to the entropy and its application in the study of quantum Carnot engines.
TLDR
This work expands the von Neumann entropy in powers of ℏ by using the phase-space formulation, and the zeroth-order term reproduces the Gibbs entropy, and obtains the explicit expression of the quantum corrections of the entropy. Expand

TLDR
This work studies the Caldeira-Leggett model where a quantum Brownian particle interacts with an environment or a bath consisting of a collection of harmonic oscillators in the path-integral formalism and derives the influence functional explicitly in this setting, which captures the effect of the coupling to the bath.

Nonequilibrium Green's Function's Approach to the Calculation of Work Statistics.
TLDR
This work proposes the contour-integral formulation for work statistics and shows how to do the perturbation expansion of the characteristic function of work and obtain the approximate expression of the CFW to the second order of the work parameter for an arbitrary system under a perturbative protocol.

TLDR
A characteristic function method is presented to calculate the probability density functions of the inclusive work in adiabatic two-level quantum Markovian master equations and finds that the fluctuation properties of the work can be described by the symmetry of the characteristic functions, which is exactly the same as in the case of isolated systems.
