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…
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…
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…
Controlling periodic Fano resonances of quantum acoustic waves with a giant atom coupled to microwave waveguide
Po-Chen Kuo, Jhen-Dong Lin, Yin-Chun Huang +1
Nanoscale Fano resonances, with applications from telecommunications to ultra-sensitive biosensing, have prompted extensive research. We demonstrate that a superconducting qubit, j…
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…
Kondo QED: The Kondo effect and photon trapping in a two-impurity Anderson model ultra-strongly coupled to light
Po-Chen Kuo, Neill Lambert, Mauro Cirio +3
The Kondo effect is one of the most studied examples of strongly correlated quantum many-body physics. Another type of strongly correlated physics that has only recently been explo…
A pseudo-fermion method for the exact description of fermionic environments: from single-molecule electronics to Kondo resonance
Mauro Cirio, Neill Lambert, Pengfei Liang +5
We develop a discrete fermion approach for modelling the strong interaction of an arbitrary system interacting with continuum electronic reservoirs. The approach is based on a pseu…
The Fermionic influence superoperator: a canonical derivation for the development of methods to simulate the influence of a Fermionic environment on a quantum system with arbitrary parity symmetry
Mauro Cirio, Po-Chen Kuo, Yueh-Nan Chen +2
We present a canonical derivation of an influence superoperator which generates the reduced dynamics of a Fermionic quantum system linearly coupled to a Fermionic environment initi…
Hidden nonmacrorealism: reviving the Leggett-Garg inequality with stochastic operations
Huan-Yu Ku, Hao-Cheng Weng, Yen-An Shih +5
The Leggett-Garg inequality (LGI) distinguishes nonmacrorealistic channels from macrorealistic ones by constraining the experimental outcomes of the underlying system. In this work…
Probing higher-order transitions through scattering of microwave photons in the ultrastrong-coupling regime of circuit QED
Guan-Ting Chen, Po-Chen Kuo, Huan-Yu Ku +2
Higher-order transitions can occur in the ultrastrong-coupling regime of circuit QED through virtual processes governed by the counter-rotating interactions. We propose a feasible…
