Quantum Spinon Oscillations
Zi Cai, Lei Wang, X. C. Xie +4
The full quantum dynamics of a spinon under external magnetic fields is investigated by using the time-evolving block decimation (TEBD) method within the microcanonical picture of…
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…
Conservation laws of the Haldane-Shastry type spin chains
Junpeng Cao, Peng He, Yuzhu Jiang +1
A systematic method to construct the complete set of conserved quantities of the Haldane-Shastry type spin chains is proposed. The hidden relationship between the Yang-Baxter relat…
Exact solution for infinitely strongly interacting Fermi gases in tight waveguides
Liming Guan, Shu Chen, Yupeng Wang +1
We present an exact analytical solution of the fundamental systems of quasi-one-dimensional spin-1/2 fermions with infinite repulsion for arbitrary confining potential. The eigenfu…
Two-dimensional spin-1 frustrated Heisenberg model with valence-bond ground states
Zi Cai, Shu Chen, Supeng Kou +1
In this paper, we propose a method to understand the nature for the quantum disorder phase of the two-dimensional (2D) high spin frustrated model. The ground state and excitation p…
