Adiabatic approximation for three qubits ultrastrongly coupled to a harmonic oscillator
Li-Tuo Shen, Rong-Xin Chen, Huai-Zhi Wu +1
We study the system involving mutual interaction between three qubits and an oscillator within the ultrastrong coupling regime. We apply adiabatic approximation approach to explore…

Ground state of the asymmetric Rabi model in the ultrastrong coupling regime
Li-Tuo Shen, Zhen-Biao Yang, Mei Lu +2
We study the ground states of the single- and two-qubit asymmetric Rabi models, in which the qubit-oscillator coupling strengths for the counterrotating-wave and corotating-wave in…

Ground state of three qubits coupled to a harmonic oscillator with ultrastrong coupling
Li-Tuo Shen, Zhen-Biao Yang, Rong-Xin Chen
We study the Rabi model composed of three qubits coupled to a harmonic oscillator without involving the rotating-wave approximation. We show that the ground state of the three-qubi…
