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…
Quantitative determination of the orbital-selective Mott transition and quantum entanglement in the orbital-selective Mott phase
Yuekun Niu, Yu Ni, Haishan Zhang +5
We examine the orbital-selective Mott transition in the non-hybridized two-band Hubbard model using the dynamical mean-field theory. We find that the orbital-selective Mott transit…
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…
Doublon-holon excitations split by Hund's rule coupling within the orbital-selective Mott phase
Yuekun Niu, Jian Sun, Yu Ni +3
Multiorbital interactions have the capacity to produce an interesting kind of doublon-holon bound state that consists of a single-hole state in one band and a doubly-occupied state…
Impact of Anisotropy on Antiferromagnet Rotation in Heusler-type Ferromagnet/Antiferromagnet Epitaxial Bilayers
T. Hajiri, M. Matsushita, Y. Z. Ni +1
We report the magnetotransport properties of ferromagnet (FM)/antiferromagnet (AFM) FeCrSi/RuMnGe epitaxial bilayers using current-in-plane configurations. Above the critic…
