Identifying the ground state phases by spin-patterns in the Shastry-Sutherland model
Yun-Tong Yang, Fu-Zhou Chen, Hong-Gang Luo
Exploring the influence of frustration on the phases and related phase transitions in condensed matter physics is of fundamental importance in uncovering the role played by frustra…

An explicit evolution from Néel to striped antiferromagnetic states in the spin-1/2 - Heisenberg model on the square lattice
Yun-Tong Yang, Fu-Zhou Chen, Chen Cheng +1
The frustrated spin- Heisenberg model on the square lattice has been extensively studied since 1988 because of its close relationship to the high-temperature superco…

Magnetization jump in one dimensional model with anisotropic exchange
Bin-Bin Mao, Chen Cheng, Fu-Zhou Chen +1
We investigate the adiabatic magnetization process of the one-dimensional model with XXZ anisotropy in an external magnetic field by using density matrix renormal…
