Multimode Brownian oscillators: Exact solutions to heat transport
Xin-Hai Tong, Hong Gong, Yao Wang +2
In this work, we investigate the multimode Brownian oscillators in nonequilibrium scenarios with multiple reservoirs at different temperatures. For this purpose, an algebraic metho…
Nonequilibrium work distributions in quantum impurity system-bath mixing processes
Hong Gong, Yao Wang, Xiao Zheng +2
The fluctuation theorem, where the central quantity is the work distribution, is an important characterization of nonequilibrium thermodynamics. In this work, based on the dissipat…
Temperature-dependence of the subdivision potential in nanothermodynamics
Yu Su, Zi-Fan Zhu, Hong Gong +3
Nanothermodynamics is the thermodynamics of small systems, which are signifcantly affected by their surrounding environments. In nanothermodynamics, Hill introduced the concept of…
A statistical quasi-particles thermofield theory with Gaussian environments: System-bath entanglement theorem for nonequilibrium correlation functions
Yao Wang, Zi-Hao Chen, Rui-Xue Xu +2
For open quantum systems, the Gaussian environmental dissipative effect can be represented by statistical quasi-particles, namely, dissipatons. We exploit this fact to establish th…
Equilibrium and transient thermodynamics: A unified dissipaton-space approach
Hong Gong, Yao Wang, Hou-Dao Zhang +4
This work presents a unified dissipaton-equation-of-motion (DEOM) theory and its evaluations on the Helmholtz free energy change due to the isotherm mixing of two isolated subsyste…
System-bath entanglement theorem with Gaussian environments
Peng-Li Du, Yao Wang, Rui-Xue Xu +2
In this work, we establish a so-called "system-bath entanglement theorem", for arbitrary systems coupled with Gaussian environments. This theorem connects the entangled system-bath…
Hierarchical dynamics for system-bath coherence correlation spectrum
Hou-Dao Zhang, Jian Xu, Rui-Xue Xu +2
We propose a quasi-particle description for the hierarchical equations of motion formalism for quantum dissipative dynamics systems. Not only it provides an alternative mathematica…
Hierarchical theory of quantum dissipation: Partial fraction decomposition scheme
Jian Xu, Rui-Xue Xu, Meng Luo +1
We propose a partial fraction decomposition scheme to the construction of hierarchical equations of motion theory for bosonic quantum dissipation systems. The expansion of Bose--Ei…
Hierarchical quantum master equation with semiclassical Drude dissipation
Rui-Xue Xu, Bao-Ling Tian, Jian Xu +2
We propose a nonperturbative quantum dissipation theory, in term of hierarchical quantum master equation. It may be used with a great degree of confidence to various dynamics syste…
Exact quantum dissipative dynamics under external time-dependent fields driving
Jian Xu, Rui-Xue Xu, YiJing Yan
Exact and nonperturbative quantum master equation can be constructed via the calculus on path integral. It results in hierarchical equations of motion for the reduced density opera…
Exact dynamics of driven Brownian oscillators
Rui-Xue Xu, Bao-Ling Tian, Jian Xu +1
Exact quantum master equation for a driven Brownian oscillator system is constructed via a Wigner phase-space Gaussian wave packet approach. The interplay between external field an…
