Emission spectral non-Markovianity in qubit-cavity systems in the ultrastrong coupling regime
Chenyi Zhang, Minghong Yu, Yiying Yan +3
We study the emission spectra of dissipative Rabi and Jaynes-Cummings models in the non-Markovian and ultrastrong coupling regimes. We have derived a polaron-transformed Nakajima-Z…
Lamb Shift and the Vacuum Rabi Splitting in a Strongly Dissipative Environment
Yiying Yan, Tadele T. Ergogo, Zhiguo Lü +3
We study the vacuum Rabi splitting of a qubit ultrastrongly coupled to a high- cavity mode and a radiation reservoir. Three methods are employed: a numerically exact variational…
Schrödinger-cat states in Landau-Zener-Stückelberg-Majorana interferometry: a multiple Davydov Ansatz approach
Lu Wang, Fulu Zheng, Jiaming Wang +2
Employing the time-dependent variational principle combined with the multiple Davydov Ansatz, we investigate Landau-Zener (LZ) transitions in a qubit coupled to a ph…
Photon-assisted Landau-Zener transitions in a periodically driven Rabi dimer coupled to a dissipative mode
Fulu Zheng, Yuejun Shen, Kewei Sun +1
We investigate multiple photon-assisted Landau-Zener (LZ) transitions in a hybrid circuit quantum electrodynamics device in which each of two interacting transmission-line resonato…
Variational approach to time-dependent fluorescence of a driven qubit
Yiying Yan, Lipeng Chen, JunYan Luo +1
We employ the Dirac-Frenkel variational principle and multiple Davydov ansatz to study time-dependent fluorescence spectra of a driven qubit in the weak- to strong qubit-reservoir…
Signatures of many-body localization and metastability by weak perturbation
Yang Zhao, Rajesh Narayanan, Jaeyoon Cho
Nonequilibrium dynamics in isolated quantum many-body systems displays a number of intriguing features, such as many-body localization (MBL) and prethermalization. Here we investig…
