Von Neumann Entropy Spectra and Entangled Excitations in Spin-Orbital Models
Wen-Long You, Andrzej M. Oleś, Peter Horsch
We consider the low-energy excitations of one-dimensional spin-orbital models which consist of spin waves, orbital waves, and joint spin-orbital excitations. Among the latter we id…

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…
