Resonance of Geometric Quantities and Hidden Symmetry in the Asymmetric Rabi Model
Qinjing Yu, Zhiguo Lü
We present the interesting resonance of two kinds of geometric quantities, namely the Aharonov-Anandan (AA) phase and the time-energy uncertainty, and reveal the relation between r…
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…
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…
Effects of counterrotating interaction on driven tunneling dynamics: coherent destruction of tunneling and Bloch-Siegert shift
Zhiguo Lü, Hang Zheng
We investigate the dynamics of a driven two-level system (classical Rabi model) using the counter-rotating-hybridized rotating wave method (CHRW), which is a simple method based on…
Quantum Zeno and anti-Zeno effects in open quantum systems
Zixian Zhou, Zhiguo Lü, Hang Zheng +1
Traditional approach on quantum Zeno effect (QZE) and quantum anti-Zeno effect (QAZE) in open quantum systems (implicitly) assumes the bath (environment) state returning to its ori…
Topology-Induced Symmetry Breaking for Vortex with Artificial Monopole
Zixian Zhou, Zhiguo Lü, Hang Zheng
We construct an artificial U(1) gauge field in the cold atom system to form a monopole along with vortices. It is supposed that the cold atoms are confined on a spherical surface,…
