General phase diagram features of superradiant phase transitions
Wen Zhao, Junlong Tian, Jie Peng
Various light-matter interactions lead to diverse phase diagram structures in superradiant phase transition (SPT) studies. Such systems consist of multiqubit and multimode with ani…
Dissipation-assisted few-photon optical diode
Teng-Fei Xiao, Junlong Tian, Jie Peng
We studied the coherent transport of one or two photons in a one-dimensional waveguide chirally coupled to a dissipative nonlinear cavity. The scattering amplitudes were derived an…
Deterministic two-photon C-Z gate with the two-photon quantum Rabi model
Jia-Cheng Tang, Jin Zhao, Haitao Yang +5
We propose a scheme for realizing a deterministic two-photon C-Z gate based on variants of the two-photon quantum Rabi model (QRM), which is feasible within the framework of circui…
Dark-state solution and symmetries of the two-qubit multimode asymmetric quantum Rabi model
Ze-Feng Lei, Junlong Tian, Jie Peng
We study the two-qubit asymmetric quantum Rabi model (AQRM) and find its dark-state solution. Such solutions have at most one photon and constant eigenenergy in the whole coupling…
N-photon solutions to the two-qubit quantum Rabi model
Qiang Lin, Junlong Tian, Pinghua Tang +1
We studied the two-qubit quantum Rabi model and found its dark state solutions with at most N photons. One peculiar case presents when , which has constant eigenenergy in the…
