Anomalous Orbital Reconstruction Controlled by Interorbital Correlations and Hund's Coupling

Yu Ni, Lvjin Wang, Jinfeng Wang +3

The microscopic origin of anomalous orbital polarization in a class of low-dimensional correlated oxides remains unresolved due to the competition among crystal-field effects, elec…

Local Spin Excitations Mediate Quasiparticle Breakdown in the Orbital-Selective Mott Phase

Yuekun Niu, Yu Ni, Jia-Ming Wang +3

The orbital-selective Mott phase (OSMP) is commonly described as a coexistence of localized and itinerant electrons within effectively decoupled orbitals, but emerging evidence for…

Evolution between two orbital-selective Mott phases driven by interorbital hopping

Yu Ni, Jian Sun, Ya-Min Quan +1

The effect of interorbital hopping on the orbital selective Mottness in a two-band correlation system is investigated by using the dynamical mean-field theory with the Lanczos meth…

Quantitative Determination of the Critical Points of Mott Metal-Insulator Transition in Strongly Correlated Systems

Yuekun Niu, Yu Ni, Jianli Wang +4

Mottness is at the heart of the essential physics in a strongly correlated system as many novel quantum phenomena occur in the metallic phase near the Mott metal-insulator transiti…

Electronic correlation-driven orbital polarization transitions in the orbital-selective Mott compound BaCuO

Yu Ni, Ya-Min Quan, Jingyi Liu +2

The electronic states near the Fermi level of recently discovered superconductor BaCuO consist primarily of the Cu and orbitals. We investi…

A dynamical mean-field study of orbital-selective Mott phase enhanced by next-nearest neighbor hopping

Yuekun Niu, Jian Sun, Yu Ni +1

The dynamical mean-field theory is employed to study the orbital-selective Mott transition (OSMT) of the two-orbital Hubbard model with nearest neighbor hopping and next-nearest ne…
