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…
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…
The study of doubly charmed pentaquark with the SU(3) symmetry
Ye Xing, Yuekun Niu
We study the masses and lifetimes of doubly charmed pentaquark primarily. The operation of masses carried out by the doubly heavy triquark-diquark model,…
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…
Bosonic edge states in gapped honeycomb lattices
Huaiming Guo, Yuekun Niu, Shu Chen +1
By quantum Monte Carlo simulations of bosons in gapped honeycomb lattices, we show the existence of bosonic edge states. For single layer honeycomb lattice, bosonic edge states can…
