Electronic correlation-driven orbital polarization transitions in the orbital-selective Mott compound Ba $_{2}$ CuO $_{4 - δ}$

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

The electronic states near the Fermi level of recently discovered superconductor Ba $_{2}$ CuO $_{4 - δ}$ consist primarily of the Cu $d_{x^{2} - y^{2}}$ and $d_{3 z^{2} - r^{2}}$ 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…
