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…
