Dynamical symmetry of Dirac hydrogen atom with spin symmetry and its connection with Ginocchio's oscillator
Fu-Lin Zhang, Bo Fu, Jing-Ling Chen
The Dirac hydrogen atom with spin symmetry is shown has a SO(4) symmetry. The generators are derived, and the corresponding Casimir operator leads to the energy spectrum naturally.…
Exact Solution of a Yang-Baxter Spin-1/2 Chain Model and Quantum Entanglement
Ming-Guang Hu, Kang Xue, Mo-Lin Ge
Entanglement is believed to be crucial in macroscopic physical systems for understanding the collective quantum phenomena such as quantum phase transitions. We start from and solve…
Berry phase and quantum criticality in Yang--Baxter systems
Jing-Ling Chen, Kang Xue, Mo-Lin Ge
Spin interaction Hamiltonians are obtained from the unitary Yang--Baxter -matrix. Based on which, we study Berry phase and quantum criticality in the Yang--Baxter system…
Dynamical symmetries of two-dimensional systems in relativistic quantum mechanics
Fu-Lin Zhang, Ci Song, Jing-Ling Chen
The two-dimensional Dirac Hamiltonian with equal scalar and vector potentials has been proved commuting with the deformed orbital angular momentum . When the potential takes the…
Berry's phase for coherent states of Landau levels
Wen-Long Yang, Jing-Ling Chen
The Berry phases for coherent states and squeezed coherent states of Landau levels are calculated. Coherent states of Landau levels are interpreted as a result of a magnetic flux m…
Intermediate-statistics quantum bracket, coherent state, oscillator, and representation of angular momentum (su(2)) algebra
Yao Shen, Wu-Sheng Dai, Mi Xie
In this paper, we first discuss the general properties of an intermediate-statistics quantum bracket, , which corresponds to intermediate statistics…
