Entanglement Hamiltonian and effective temperature of non-Hermitian quantum spin ladders
Pei-Yun Yang, Yu-Chin Tzeng
Quantum entanglement plays a crucial role not only in understanding Hermitian many-body systems but also in offering valuable insights into non-Hermitian quantum systems. In this p…
Long-Range Non-Equilibrium Coherent Tunneling Induced by Fractional Vibronic Resonances
R. Kevin Kessing, Pei-Yun Yang, Salvatore R. Manmana +1
We study the influence of a linear energy bias on a non-equilibrium excitation on a chain of molecules coupled to local phonons (a tilted Holstein model) using both a random-walk r…
Quantum Effects in Chemical Reactions under Polaritonic Vibrational Strong Coupling
Peiyun Yang, Jianshu Cao
The electromagnetic field in an optical cavity can dramatically modify and even control chemical reactivity via vibrational strong coupling (VSC). Since the typical vibration and c…
Steady-State Analysis of Light-harvesting Energy Transfer Driven by Incoherent Light: From Dimers to Networks
Pei-Yun Yang, Jianshu Cao
The question of how quantum coherence facilitates energy transfer has been intensively debated in the scientific community. Since natural and artificial light-harvesting units oper…
Exact dynamics of the homogeneous two-qubit central spin model with the spin bath prepared in superpositions of symmetric Dicke states
Zejiang Li, Pei Yang, Wen-Long You +1
We obtain exact dynamics of a two-qubit central spin model (CSM) consisting of two interacting qubits homogeneously coupled to a spin bath via the -type coupling, with the bat…
Dissipative topological systems
Yu-Wei Huang, Pei-Yun Yang, I-Chi Chen +1
Topological phases of matter are protected from local perturbations and therefore have been thought to be robust against decoherence. However, it has not been systematically explor…
Exact master equation and decoherence dynamics of Majorana zero modes under the gate-induced charge fluctuation
Hon-Lam Lai, Pei-Yun Yang, Yu-Wei Huang +1
In this paper, we derive the exact master equation to investigate the decoherence dynamics of Majorana zero modes in the Kitaev model, a 1D -wave spinless topological supercon…
Buildup of Fano resonances in the time domain in a double quantum dot Aharonov-Bohm interferometer
Pei-Yun Yang, Wei-Min Zhang
In this paper, we investigate transient quantum transport in a nanoscale Aharonov-Bohm (AB) interferometer consisting of a laterally coupled double quantum dot (DQD) coupled to the…
Master equation approach to transient quantum transport in nanostructures
Pei-Yun Yang, Wei-Min Zhang
In this review article, we present a non-equilibrium quantum transport theory for transient electron dynamics in nanodevices based on exact master equation derived with the path in…
Non-equilibrium quantum phase transition via entanglement decoherence dynamics
Yu-Chen Lin, Pei-Yun Yang, Wei-Min Zhang
We investigate the decoherence dynamics of continuous variable entanglement as the system-environment coupling strength varies from the weak-coupling to the strong-coupling regimes…
Exact homogeneous master equation for open quantum systems incorporating initial correlations
Pei-Yun Yang, Wei-Min Zhang
We show that the exact master equation incorporating initial correlations for open quantum systems, within the Nakajima-Zwanzig operator-projection method, is a homegenous master e…
Master equation approach to transient quantum transport incorporating with initial correlations
Pei-Yun Yang, Chuan-Yu Lin, Wei-Min Zhang
In this paper, the exact transient quantum transport of non-interacting nanostructures is investigated in the presence of initial system-lead correlations and initial lead-lead cor…
Transient Current-Current Correlations and Noise Spectra
Pei-Yun Yang, Chuan-Yu Lin, Wei-Min Zhang
In this paper, we present an exact formalism for transient current-current correlations and transient noise spectra. The exact solution of transient current correlations in both th…
