Entanglement driven phase transitions in spin–orbital models
To demonstrate the role played by the von Neumann entropy (vNE) spectra in quantum phase transitions we investigate the one-dimensional anisotropic SU(2) $\otimes \mathrm{XXZ}$ spin–orbital model with negative exchange parameter. In the case of classical Ising orbital interactions we discover an une...
