Variational approach to light-matter interaction: Bridging quantum and semiclassical limits
Yiying Yan, Zhiguo Lü, JunYan Luo
We present a time-dependent variational approach with the multiple Davydov trial state to simulate the dynamics of light-matter systems when the field is in a coherent state…
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…
Dynamics of the spin-boson model: the effect of bath initial conditions
Lipeng Chen, Yiying Yan, Maxim F. Gelin +1
Dynamics of the (sub-)Ohmic spin-boson model under various bath initial conditions is investigated by employing the Dirac-Frenkel time-dependent variational approach with the multi…
Sub-Ohmic spin-boson model with off-diagonal coupling: Ground state properties
Zhiguo Lu, Liwei Duan, Xin Li +2
We have carried out analytical and numerical studies of the spin-boson model in the sub-ohmic regime with the influence of both the diagonal and off-diagonal coupling accounted for…
