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…
HierarchicalEOM.jl: An efficient Julia framework for hierarchical equations of motion in open quantum systems
Yi-Te Huang, Po-Chen Kuo, Neill Lambert +5
The hierarchical equations of motion (HEOM) approach can describe the reduced dynamics of a system simultaneously coupled to multiple bosonic and fermionic environments. The comple…
Non-Markovian skin effect
Po-Chen Kuo, Shen-Liang Yang, Neill Lambert +4
The Liouvillian skin effect and the non-Hermitian skin effect have both been used to explain the localization of eigenmodes near system boundaries, though the former is arguably mo…
Non-Markovian Quantum Exceptional Points
Jhen-Dong Lin, Po-Chen Kuo, Neill Lambert +3
Exceptional points (EPs) are singularities in the spectra of non-Hermitian operators, where eigenvalues and eigenvectors coalesce. Recently, open quantum systems have been increasi…
