Phase transition and critical properties of spin-orbital interacting systems
Huai-Bao Tang, Dong-Meng Chen, Xiang-Fei Wei +1
Phase transition and critical properties of Ising-like spin-orbital interacting systems in 2-dimensional triangular lattice are investigated. We first show that the ground state of…
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…
Orthorhombic crystalline field splitting on orbital and magnetic orders in KCuF
Dong-Meng Chen, Liang-Jian Zou
Magnetic and orbital structures in KCuF are revisited by the cluster self-consistent field approach developed recently. We clearly showed that due to the inherent frustration…
Orbital Insulators and Orbital Order-disorder Induced Metal-Insulator Transition in Transition-Metal Oxides
Dong-Meng Chen, Liang-Jian Zou
The role of orbital ordering on metal-insulator transition of transition-metal oxides is investigated by the cluster self-consistent field approach in the strong correlation regime…
