Engineered Tunable Decay Rate and Controllable Dissipative Dynamics
Zhiguo Lü, Hang Zheng
We investigate the steering dissipative dynamics of a two-level system (qubit) by means of the modulation of an assisted tunneling degree of freedom which is described by a quantum…
Geometric phase and non-adiabatic resonance of the Rabi model
Sijiang Liu, Zhiguo Lü, Hang Zheng
We investigate the effects of counterrotating terms on geometric phase and its relation to the resonance of the Rabi model. We apply the unitary transformation with a single parame…
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…
Variational study of two-impurity spin-boson model with a common Ohmic bath: Ground-state phase transitions
Nengji Zhou, Yuyu Zhang, Zhiguo Lu +1
By means of a trial wave function, the multi-D ansatz, extensive variational calculations with more than ten thousand parameters have been carried out to study quantum phase tr…
Protecting coherence by reservoir engineering: intense bath disturbance
Zixian Zhou, Zhiguo Lü, Hang Zheng
We put forward a scheme based on reservoir engineering to protect quantum coherence from leaking to bath, in which we intensely disturb the Lorentzian bath by N harmonic oscillator…
