Quantum phase transitions in spin-1 compass chains
Guang-Hua Liu, Long-Juan Kong, Wen-Long You
The ground-state phase diagram and quantum phase transitions (QPTs) in a spin-1 compass chain are investigated by the infinite time-evolving block decimation (iTEBD) method. Variou…
Entanglement entropy and fidelity susceptibility in the one-dimensional spin-1 XXZ chains with alternating single-site anisotropy
Jie Ren, Guang-Hua Liu, Wen-Long You
We study the fidelity susceptibility in an antiferromagnetic spin-1 XXZ chain numerically. By using the density-matrix renormalization group method, the effects of the alternating…
Quantum phase transitions and string orders in the spin-1/2 Heisenberg-Ising alternating chain with Dzyaloshinskii-Moriya interaction
Guang-Hua Liu, Wen-Long You, Wei Li +1
Quantum phase transitions (QPTs) and the ground-state phase diagram of the spin-1/2 Heisenberg-Ising alternating chain (HIAC) with uniform Dzyaloshinskii-Moriya (DM) interaction ar…
Exact treatment of magnetism-driven ferroelectricity in the one-dimensional compass model
Wen-Long You, Guang-Hua Liu, Peter Horsch +1
We consider a class of one-dimensional compass models with antisymmetric Dzyaloshinskii-Moriya exchange interaction in an external magnetic field. Based on the exact solution deriv…
Matrix Product State and Quantum Phase Transitions in the One-Dimensional Extended Quantum Compass Model
Guang-Hua Liu, Wei Li, Wen-Long You +2
The matrix product state (MPS) is utilized to study the ground state properties and quantum phase transitions (QPTs) of the one-dimensional quantum compass model (QCM). The MPS wav…
