Orbital Order Instability and Orbital Excitations in Degenerate Itinerant Electron Systems
Feng Lu, Dong-meng Chen, Liang-Jian Zou
We present the theory of orbital ordering in orbital-degenerate itinerant electron systems. After proposing the criterion of instability for orbital ordering or orbital density wav…

Entanglements in Systems with Multiple Degrees of Freedom
Dong-Meng Chen, Wei-Hua Wang, Liang-Jian Zou
We present the entanglement properties of the spin-orbital coupling systems with multiple degrees of freedom. After constructing the maximally entangled spin-orbital basis of bipar…
