Spectral continuum in the Rabi-Stark model
Daniel Braak, Lei Cong, Hans-Peter Eckle +2
The Rabi-Stark model is a non-linear generalization of the quantum Rabi model including the dynamical Stark shift as a tunable term, which can be realized via quantum simulation on…
Entanglement resonance in the asymmetric quantum Rabi model
Yu-Qing Shi, Lei Cong, Hans-Peter Eckle
We investigate the entanglement features in the interacting system of a quantized optical field and a two-level system which is statically driven, known as the asymmetric quantum R…
Selective Interactions in the Quantum Rabi Model
L. Cong, S. Felicetti, J. Casanova +3
We demonstrate the emergence of selective -photon interactions in the strong and ultrastrong coupling regimes of the quantum Rabi model with a Stark coupling term. In particular…
Polaron picture of the two-photon quantum Rabi model
Lei Cong, Xi-Mei Sun, Maoxin Liu +2
We employ a polaron picture to investigate the properties of the two-photon quantum Rabi model (QRM), which describes a two-level or spin-half system coupled with a single bosonic…
Quantum phase transition and spontaneous symmetry breaking in a nonlinear quantum Rabi model
Zu-Jian Ying, Lei Cong, Xi-Mei Sun
The experimental advance on light-matter interaction into strong couplings has invalidated Jaynes-Cummings model and brought quantum Rabi model (QRM) to more relevance. The QRM onl…
Frequency-renormalized multipolaron expansion for the quantum Rabi model
Lei Cong, Xi-Mei Sun, Maoxin Liu +2
We present a frequency-renormalized multipolaron expansion method to explore the ground state of quantum Rabi model (QRM). The main idea is to take polaron as starting point to exp…
