adapol: Adaptive pole-fitting for quantum many-body physics
Zhen Huang, Chia-Nan Yeh, Lin Lin +3
We describe adapol, a Python package for fitting Matsubara Green's functions, self-energies, and hybridization functions by a compact sum of simple poles with real pole locations a…
Provably Efficient Long-Time Exponential Decompositions of Non-Markovian Gaussian Baths
Zhen Huang, Zhiyan Ding, Ke Wang +3
Gaussian baths are widely used to model non-Markovian environments, yet the cost of accurate simulation at long times remains poorly understood, especially when spectral densities…
Coupled Lindblad pseudomode theory for simulating open quantum systems
Zhen Huang, Gunhee Park, Garnet Kin-Lic Chan +1
Coupled Lindblad pseudomode theory is a promising approach for simulating non-Markovian quantum dynamics on both classical and quantum platforms, with dynamics that can be realized…
Unified error bounds for perturbations of non-Markovian open quantum systems in Gaussian environments
Zhen Huang, Yuanran Zhu, Gunhee Park +1
We present perturbative error bounds for the non-Markovian dynamics of observables in open quantum systems interacting with Gaussian environments, governed by a general Liouville d…
Quasi-Lindblad pseudomode theory for open quantum systems
Gunhee Park, Zhen Huang, Yuanran Zhu +3
We introduce a new framework to study the dynamics of open quantum systems with linearly coupled Gaussian baths. Our approach replaces the continuous bath with an auxiliary discret…
