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…
Phase diagram of frustrated mixed-spin ladders in the strong-coupling limit
Shu Chen, Li Wang, Yupeng Wang
We study the ground-state properties of frustrated Heisenberg ferrimagnetic ladders with antiferromagnetic exchange interactions and two types of alternating sublattice spins. In t…
Ground-state Competition of Two-Component Bosons in Optical Lattice near a Feshbach Resonance
Liping Guo, Yunbo Zhang, Shu Chen
We investigate the ground state properties of an equal mixture of two species of bosons in its Mott-insulator phase at a filling factor two per site. We identify one type of spin t…
Ground-state properties of one-dimensional ultracold Bose gases in a hard-wall trap
Yajiang Hao, Yunbo Zhang, J. -Q. Liang +1
We investigate the ground state of the system of N bosons enclosed in a hard-wall trap interacting via a repulsive or attractive -function potential. Based on the Bethe ansatz m…
One-dimensional spin pyrochlore lattice: exact ground state and elementary excitations
Shu Chen, Yupeng Wang, W. Q. Ning +2
We study the antiferromagnetic spin exchange models with and S=1 on a one-dimensional tetrahedron chain by both analytical and numerical approaches. The system is shown to…
