RC-HEOM Hybrid Method for Non-Perturbative Open System Dynamics
Po-Rong Lai, Jhen-Dong Lin, Yi-Te Huang +3
The Hierarchical equations of motion (HEOM) method is an important non-perturbative technique, allowing numerically exact treatment of open quantum systems with strong coupling and…
Exact description of fermionic reservoirs via purified damped ancillary fermions
Pengfei Liang, Neill Lambert, Mauro Cirio
We present a method for the modeling of fermionic reservoirs using a new class of ancillary damped fermions, dubbed purified pseudofermions, which exhibit unusual free correlations…
Purified pseudomode model for nonlinear system-bath interactions
Cheng Zhang, Neill Lambert, Xin-Qi Li +2
The theory of purified pseudomodes [arXiv:2412.04264 (2024)] was recently developed to provide a numerical tool for the analysis of the properties of a quantum system and the envir…
Input-Output Hierarchical Equations Of Motion
Mauro Cirio, Pengfei Liang, Neill Lambert
We derive an extended version of the hierarchical equations of motion (HEOM) to compute output physical properties of a bosonic environment, which is allowed to be initially prepar…
A purified input-output pseudomode model for structured open quantum systems
Pengfei Liang, Neill Lambert, Si Luo +2
A full understanding of open quantum systems requires the characterization of both system and environmental properties. However, the complexity of the environmental statistics in t…
