Multiphoton resonance band and Bloch-Siegert shift in a bichromatically driven qubit
Yiying Yan, Zhiguo Lü, Lipeng Chen +1
We study the resonance and dynamics of a qubit exposed to a strong aperiodic bichromatic field by using a periodic counter-rotating hybridized rotating wave (CHRW) Hamiltonian, whi…

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…
