Plateau dynamics with quantized oscillations of a strongly driven qubit
Yejia Chen, Zhiguo Lü, Yiying Yan +1
We present an interesting dynamical temporal localization of a strongly driven two-level system (TLS), a plateau with quantized oscillation, by an analytical and transparent method…
Variational approach to time-dependent fluorescence of a driven qubit
Yiying Yan, Lipeng Chen, JunYan Luo +1
We employ the Dirac-Frenkel variational principle and multiple Davydov ansatz to study time-dependent fluorescence spectra of a driven qubit in the weak- to strong qubit-reservoir…
Role of generalized parity in the symmetry of fluorescence spectrum from two-level systems under periodic frequency modulation
Yiying Yan, Zhiguo Lü, JunYan Luo +1
We study the origin of the symmetry of the fluorescence spectrum from the two-level system subjected to a low-frequency periodic modulation and a near-resonant high-frequency monoc…
Stochastic thermodynamics of an electron-spin-resonance quantum dot system
JunYan Luo, Yiying Yan, Hailong Wang +3
We present a stochastic thermodynamics analysis of an electron-spin-resonance pumped quantum dot device in the Coulomb-blocked regime, where a pure spin current is generated withou…
Bias-modulated dynamics of a strongly driven two-level system
Zhiguo Lü, Yiying Yan, Hsi-Sheng Goan +1
We investigate the bias-modulated dynamics of a strongly driven two-level system using the counter-rotating-hybridized rotating-wave (CHRW) method. This CHRW method treats the driv…
