Surface Hopping, Electron Translation Factors, Electron Rotation Factors, Momentum Conservation, and Size Consistency
Vishikh Athavale, Xuezhi Bian, Zhen Tao +5
For a system without spin-orbit coupling, the (i) nuclear plus electronic linear momentum and (ii) nuclear plus orbital electronic angular momentum are good quantum numbers. Thus,…
Symmetric Post-Transition-State Bifurcation Reactions with Berry Pseudo-Magnetic Fields
Zhen Tao, Tian Qiu, Joseph E. Subotnik
We investigate how the Berry force (i.e. the pseudo-magnetic force operating on nuclei as induced by electronic degeneracy and spin-orbit coupling (SOC)) might modify a post-transi…
On the Meaning of Berry Force For Unrestricted Systems Treated With Mean-Field Electronic Structure
Xuezhi Bian, Tian Qiu, Junhan Chen +1
We show that the Berry force as computed by an approximate, mean-field electronic structure can be meaningful if properly interpreted. In particular, for a model Hamiltonian repres…
Quantum-classical correspondence principle for heat distribution in quantum Brownian motion
Jin-Fu Chen, Tian Qiu, H. T. Quan
Quantum Brownian motion, described by the Caldeira-Leggett model, brings insights to understand phenomena and essence of quantum thermodynamics, especially the quantum work and hea…
Quantum corrections to the entropy in a driven quantum Brownian motion model
Tian Qiu, H. T. Quan
Quantum Brownian motion model is a typical model in the study of nonequilibrium quantum thermodynamics. Entropy is one of the most fundamental physical concepts in thermodynamics.…
Quantum corrections to the entropy and its application in the study of quantum Carnot engines
Tian Qiu, Zhaoyu Fei, Rui Pan +1
Entropy is one of the most basic concepts in thermodynamics and statistical mechanics. The most widely used definition of statistical mechanical entropy for a quantum system is int…
Path integral approach to the calculation of the characteristic function of work
Tian Qiu, Zhaoyu Fei, Rui Pan +1
Work statistics characterizes important features of a non-equilibrium thermodynamic process. But the calculation of the work statistics in an arbitrary non-equilibrium process is u…
Quantum-classical correspondence of work distributions for initial states with quantum coherence
Rui Pan, Zhaoyu Fei, Tian Qiu +2
The standard definition of quantum fluctuating work is based on the two-projective energy measurement, which however does not apply to systems with initial quantum coherence becaus…
Quantum work distributions associated with the dynamical Casimir effect
Zhaoyu Fei, Jing-Ning Zhang, Rui Pan +2
We study the joint probability distribution function of the work and the change of photon number of the nonequilibrium process of driving the electromagnetic (EM) field in a three-…
Quantifying the validity and breakdown of the overdamped approximation in stochastic thermodynamics: Theory and experiment
Rui Pan, Thai M. Hoang, Zhaoyu Fei +4
Stochastic thermodynamics provides an important framework to explore small physical systems where thermal fluctuations are inevitable. In the studies of stochastic thermodynamics,…
Synchronization of phase oscillators with frequency-weighted coupling
Can Xu, Yuting Sun, Jian Gao +3
Recently, the first-order synchronization transition has been studied in systems of coupled phase oscillators. In this paper, we propose a framework to investigate the synchronizat…
Landau damping effects in the synchronization of conformist and contrarian oscillators
Tian Qiu, Yue Zhang, Jie Liu +4
Two decades ago, a phenomenon resembling Landau damping was described in the synchronization of globally coupled oscillators: the evidence of a regime where the order parameter dec…
