Parametric interaction induced avoided dressed state crossings in cavity QED:generation of quantum coherence and equally weighted superposition of Fock states
L. L. Ping, W. Li, C. J. Zhu +2
We present a new paradigm in the field of cavity QED by bringing out remarkable features associated with the avoided crossing of the dressed state levels of the Jaynes Cummings mod…

Squeezed light induced symmetry breaking superradiant phase transition
Chengjie Zhu, Leilei Ping, Yaping Yang +1
We theoretically investigate the quantum phase transition in the collective systems of qubits in a high-quality cavity, which is driven by a squeezed light. We show that the squeez…
