Exact solvability of the quantum Rabi models within Bogoliubov operators
Qing-Hu Chen, Chen Wang, Shu He +2
The quantum Rabi model can be solved exactly by the Bargmann transformation from real coordinate to complex variable recently [Phys. Rev. Lett. \textbf{107}, 100401 (2011)]. By the…
Network analyzer measurements of spin transfer torques in magnetic tunnel junctions
Lin Xue, Chen Wang, Yong-Tao Cui +3
We demonstrate a simple network-analyzer technique to make quantitative measurements of the bias dependence of spin torque in a magnetic tunnel junction. We apply a microwave curre…
Resonance Measurement of Nonlocal Spin Torque in a Three-Terminal Magnetic Device
Lin Xue, Chen Wang, Yong-Tao Cui +5
A pure spin current generated within a nonlocal spin valve can exert a spin transfer torque on a nanomagnet. This nonlocal torque enables new design schemes for magnetic memory dev…
Quantum discord dynamics of two qubits in the single-mode cavities
Chen Wang, Qing-Hu Chen
The dynamics of the quantum discord for two identical qubits in both two independent single-mode cavities and a common single-mode cavity are discussed. For the initial Bell state…
Quantum correlations in the collective spin systems
Chen Wang, Yu-Yu Zhang, Qing-Hu Chen
Quantum and classical pairwise correlations in two typical collective spin systems (i.e., the Dicke model and the Lipkin-Meshkov-Glick model) are discussed. These correlations in t…
