Orbital Selective Phase Transition
Yao Yao, Yu-Zhong Zhang, Hunpyo Lee +4
We review theoretical investigations on the origin of the orbital selective phase where localized and itinerant electrons coexist in the d shell at intermediate strength of the on-…
Magnetoresistance from quenching of spin quantum correlation in organic semiconductors
Wei Si, Yao Yao, Xiaoyuan Hou +1
We present a theory of organic magnetoresistance (OMR) based on the quenching of the quantum correlation between the carrier's spin and its local environment when the incoherent ho…
Thermalization Breakdown and Conductivity Improvement within the Interacting Dynamic Disorder Model
Yao Yao, Yiqiang Zhan, Xiaoyuan Hou +1
Based on the framework of Kubo formulism, we develop the minimally entangled typical thermal state algorithm to study the temperature and time dependence of current-current correla…
Nonequilibrium electronic transport through a polymer chain: Role of solitons
Jia Wang, Yue Yang, Yao Yao +1
Nonequilibrium electronic transport through a polymer chain is investigated by the scattering state operator method. The polymer chain is described by an electron-lattice coupling…
Modeling the underlying mechanisms for organic memory devices: Tunneling, electron emission and oxygen adsorbing
Yao Yao, Yintao You, Wei Si +1
We present a combined experimental and theoretical study to get insight into both memory and negative differential resistance (NDR) effect in organic memory devices. The theoretica…
A General Mechanism for Orbital Selective Phase Transitions
Yu-Zhong Zhang, Hunpyo Lee, Hai-Qing Lin +3
Based on the analysis of a two-orbital Hubbard model within a mean-field approach, we propose a mechanism for an orbital selective phase transition (OSPT) where coexistence of loca…
