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…
Quantum entanglement in the one-dimensional spin-orbital SU(2) model
Wen-Long You, Peter Horsch, Andrzej M. Oleś
We investigate the phase diagram and the spin-orbital entanglement of a one-dimensional SU(2) model with SU(2) spin exchange and anisotropic orbital exchange int…
Generalized fidelity susceptibility at phase transitions
Wen-Long You, Li He
In the present work, we investigate the intrinsic relation between quantum fidelity susceptibility (QFS) and the dynamical structure factor. We give a concise proof of the QFS beyo…
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…
The scaling of entanglement entropy in a honeycomb lattice on a torus
Wen-Long You
The entanglement entropy of a noninteracting fermionic system confined to a two-dimensional honeycomb lattice on a torus is calculated. We find that the entanglement entropy can ch…
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…
