Variational approach to light-matter interaction: Bridging quantum and semiclassical limits
Yiying Yan, Zhiguo Lü, JunYan Luo
We present a time-dependent variational approach with the multiple Davydov trial state to simulate the dynamics of light-matter systems when the field is in a coherent state…
Spin-resolved counting statistics as a sensitive probe of spin correlation in transport through a quantum dot spin valve
Guanjian Hu, Shikuan Wang, Jing Hu +3
We investigate the noise in spin transport through a single quantum dot (QD) tunnel coupled to ferromagnetic electrodes with noncollinear magnetizations. Based on a spin-resolved q…
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…
