Absence of collapse in quantum Rabi oscillations
Shu He, Yang Zhao, Qing-Hu Chen
We show analytically that the collapse and revival in the population dynamics of the atom-cavity coupled system under the rotating wave approximation (RWA), valid only at very weak…
Solutions to the quantum Rabi model with two equivalent qubits
Hui Wang, Shu He, Liwei Duan +2
Using extended coherent states, an analytically exact study has been carried out for the quantum Rabi model with two equivalent qubits. Compact transcendental functions of one vari…
Entanglement dynamics of a two-qubit system coupled individually to Ohmic baths
Liwei Duan, Hui Wang, Qinghu Chen +1
Developed originally for the Holstein polaron, the Davydov D1 ansatz is an efficient, yet extremely accurate trial state for time-dependent variation of the spin-boson model [J. Ch…
Generalized rotating-wave approximation to biased qubit-oscillator systems
Yu-Yu Zhang, Qing-Hu Chen, Yang Zhao
The generalized rotating-wave approximation with counter-rotating interactions has been applied to a biased qubit-oscillator system. Analytical expressions are explicitly given for…
