Studies of Nonadiabatic Dynamics in the Singlet Fission Processes of Pentacene Dimer via Tensor Train Decomposition Method
Jiawei Peng, Deping Hu, Hong Liu +3
Singlet fission (SF) is a very significant photophysical phenomenon and possesses potential applications. In this work, we try to give the rather detailed theoretical investigation…
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…
Diabatic States,Couplings and Potential Energy Surfaces through the Block Localized Excitation Method
Peng Bao, Qiang Shi, Jiali Gao
We propose a new block localized excitation (BLE) method to directly construct diabatic excited states without the need to first compute the adiabatic states. The new method is cap…
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…
Theory of proton coupled electron transfer reactions: Assessing the Born-Oppenheimer approximation for the proton motion using an analytically solvable model
Renhui Zheng, Yuanyuan Jing, Liping Chen +1
By employing an analytically solvable model including the Duschinsky rotation effect, we investigated the applicability of the commonly used Born-Oppenheimer (BO) approximation for…
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…
