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…
