Exact solution of the two-axis two-spin Hamiltonian
Feng Pan, Yao-Zhong Zhang, Xiaohan Qi +3
Bethe ansatz solution of the two-axis two-spin Hamiltonian is derived based on the Jordan-Schwinger boson realization of the SU(2) algebra. It is shown that the solution of the Bet…
Exact solution of the two-axis countertwisting Hamiltonian for the half-integer case
Feng Pan, Yao-Zhong Zhang, Jerry P. Draayer
Bethe ansatz solutions of the two-axis countertwisting Hamiltonian for any (integer and half-integer) are derived based on the Jordan-Schwinger (differential) boson realization…
Exact solution of the two-axis countertwisting Hamiltonian
Feng Pan, Yao-Zhong Zhang, Jerry P. Draayer
It is shown that the two-axis countertwisting Hamiltonian is exactly solvable when the quantum number of the total angular momentum of the system is an integer after the Jordan-Sch…
Hidden -algebraic structure in Rabi model and its 2-photon and two-mode generalizations
Yao-Zhong Zhang
It is shown that the (driven) quantum Rabi model and its 2-photon and 2-mode generalizations possess a hidden -algebraic structure which explains the origin of the quasi-exa…
On the 2-mode and -photon quantum Rabi models
Yao-Zhong Zhang
By mapping the Hamiltonians of the two-mode and 2-photon Rabi models to differential operators in suitable Hilbert spaces of entire functions, we prove that the two models possess…
symmetric chiral Rabi model: a new -level system
Yao-Zhong Zhang
We present a new tractable quantum Rabi model for -level atoms by extending the symmetry of the two-state Rabi model. The Hamiltonian is symmetric an…
