Extended system-bath entanglement theorem for multiple bosonic or fermionic environments
Yu Su, Hao-Yang Qi, Zi-Hao Chen +3
The system-bath entanglement theorem (SBET) was established in terms of linear response functions [J. Chem. Phys. 152, 034102 (2020)] and generalized to correlation functions [arXi…
Kondo regime of the impurity spectral function and the current noise spectrum in the double impurity Anderson model
Zi-Hao Chen, YiJing Yan
The dissipaton equations of motion (DEOM) method is one of the most popular methods for simulating quantum impurity systems. In this article, we use DOEM theory to deal with the Ko…
Dissipatons as generalized Brownian particles for open quantum systems: Dissipaton-embedded quantum master equation
Xiang Li, Yu Su, Zi-Hao Chen +4
Dissipaton theory had been proposed as an exact and nonperturbative approach to deal with open quantum system dynamics, where the influence of Gaussian environment is characterized…
Spin relaxation dynamics with a continuous spin environment: the dissipaton equation of motion approach
Wenxiang Ying, Yu Su, Zi-Hao Chen +2
We present the quantum dynamics of a spin coupling to a bath of independent spins via the dissipaton equation of motion (DEOM) approach. The bath, characterized by a continuous spe…

Testing Quantum Dissipation Theory with Electron Diffraction
Raul Puente, Zilin Chen, Herman Batelaan
Decoherence can be provided by a dissipative environment as described by the Caldeira-Leggett equation. This equation is foundational to the theory of quantum dissipation. However,…
Nonequilibrium system-bath entanglement theorem versus heat transport
Peng-Li Du, Zi-Hao Chen, Yu Su +3
In this work, we extend the recently established system-bath entanglement theorem (SBET) [J. Chem. Phys. 152, 034102 (2020)] to the nonequilibrium scenario, in which an arbitrary s…
Aloof electron probing of in-plane SPV charge distributions on GaAs surfaces
Zilin Chen, Wayne Cheng-Wei Huang, Herman Batelaan
The motion of free electrons moving parallel and above a semiconductor surface can be influenced by shining laser light onto the surface. Here we report strong deflection of aloof…
