Exact Solutions of a One-dimensional Quantum Spin Chain with SO(5)-Symmetry
Yuzhu Jiang, Junpeng Cao, Yupeng Wang
A new exactly solvable one-dimensional spin-3/2 Heisenberg model with SO(5)-invariance is proposed. The eigenvalues and Bethe ansatz equations of the model are obtained by using th…

Exact solutions of an SO(5)-invariant spin-3/2 Fermi gas model
Yuzhu Jiang, Junpeng Cao, Yupeng Wang
An exactly solvable model describing the dilute spin-3/2 fermion gas in one-dimensional optical trap is proposed. The diagonalization of the model Hamiltonian is derived by means o…
