Nonreciprocal routing induced by chirality in an atom-dimer waveguide-QED system
Shi-Yu Liu, Lin-Lin Jiang, Hai Zhu +2
The implementation of quantum routers is an important and desired task in quantum information science, since quantum routers are important components of quantum networks. Here, we…

Chirally Frustrated Superradiant Phases in a Jaynes-Cummings Trimer
Lin-Lin Jiang, Xuan Xie, Lin Tian +1
We investigate the emergence of frustrated quantum phases in a Jaynes-Cummings (JC) trimer with complex hopping amplitudes between the cavities, which represents the smallest frust…

Controlling the superradiant phase transition in the quantum Rabi model
Xuan Xie, Cheng Liu, Lin-Lin Jiang +1
In the ultrastrong-coupling regime, the quantum Rabi model can exhibit quantum phase transition (QPT) when the ratio of the qubit transition frequency to the frequency of the cavit…
