Solving the Jaynes-Cummings Model with Shift Operators Constructed by Means of the Matrix-Diagonalizing Technique
Jie Zhou, Hong-Yi Su, Fu-Lin Zhang +2
The Jaynes-Cummings model is solved with the raising and lowering (shift) operators by using the matrix-diagonalizing technique. Bell nonlocality is also found present ubiquitously…
The sudden birth and sudden death of thermal fidelity in a two-qubit XY model
Li-Jun Tian, Li-Guo Qin, Ying Jiang +1
We study the energy level crossings of the states and thermal fidelity for a two-qubit system in the presence of a transverse and inhomogeneous magnetic field. It is shown clearly…
Fidelity susceptibility and geometric phase in critical phenomenon
Li-Jun Tian, Chang-Qing Zhu, Hong-Biao Zhang +1
Motivated by recent development in quantum fidelity and fidelity susceptibility, we study relations among Lie algebra, fidelity susceptibility and quantum phase transition for a tw…
Su(1,2) Algebraic Structure of the XYZ Antiferromagnetic Model in Linear Spin-Wave Frame
Shuo Jin, Bing-Hao Xie, Hong-Biao Zhang +1
The antiferromagnetic model in linear spin-wave frame is shown explicitly to have an algebraic structure: the Hamiltonian can be written as a linear function of the…
Yangian and Applications
Cheng-Ming Bai, Mo-Lin Ge, Kang Xue +1
In this paper, the Yangian relations are tremendously simplified for Yangians associated to SU(2), SU(3), SO(5) and SO(6) based on RTT relations that much benefit the realization o…
A Model for the Coexistence of p-wave Superconductivity and Ferroelectricity
Hong-Biao Zhang, Li-Jun Tian, Guo-Hong Yang +2
A model for the coexistence of p-wave superconductivity (SC) and ferroelectricity (FE) is presented. The Hamiltonian of SC sector and FE sector can be diagonalized by using the $so…
