Environment-Mediated Long-Ranged Correlations in Many-Body System
Meng Xu, J. T. Stockburger, J. Ankerhold
Quantum states in complex aggregates are unavoidably affected by environmental effects, which typically cannot be accurately modeled by simple Markovian processes. As system sizes…
About the performance of perturbative treatments of the spin-boson dynamics within the hierarchical equations of motion approach
Meng Xu, Joachim Ankerhold
The hierarchical equations of motion (HEOM) provide a numerically exact approach for simulating the dynamics of open quantum systems coupled to a harmonic bath. However, its applic…
A Universal Framework for Quantum Dissipation:Minimally Extended State Space and Exact Time-Local Dynamics
Meng Xu, Vasilii Vadimov, Malte Krug +2
The dynamics of open quantum systems is formulated in a minimally extended state space comprising the degrees of freedom of a system of interest and a finite set of non-unitary, pu…
Efficient low temperature simulations for fermionic reservoirs with the hierarchical equations of motion method: Application to the Anderson impurity model
Xiaohan Dan, Meng Xu, J. T. Stockburger +2
The hierarchical equations of motion (HEOM) approach is an accurate method to simulate open system quantum dynamics, which allows for systematic convergence to numerically exact re…
Taming Quantum Noise for Efficient Low Temperature Simulations of Open Quantum Systems
Meng Xu, Yaming Yan, Qiang Shi +2
The hierarchical equations of motion (HEOM), derived from the exact Feynman-Vernon path integral, is one of the most powerful numerical methods to simulate the dynamics of open qua…
Exact generator and its high order expansions in the time-convolutionless generalized master equation: Applications to the spin-boson model and exictation energy transfer
Yanying Liu, Yaming Yan, Meng Xu +2
The time-convolutionless (TCL) quantum master equation provides a powerful tool to simulate reduced dynamics of a quantum system coupled to a bath. The key quantity in the TCL mast…
