Reentrance of metal-insulator transition and magnetic competitions on a triangular lattice with second nearest-neighbor hopping
Xin Gao, Cong Hu, Jian Sun +3
The antiferromagnetism (AFM) is widely believed as the magnetic ground state of the triangular systems because of the geometrical frustration. The emergence of novel…
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…
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…
Localization and Orbital Selectivity in Iron-Based Superconductors with Cu Substitution
Yang Liu, Da-Yong Liu, Jiang-Long Wang +3
We study an inhomogeneous three-orbital Hubbard model for the Cu-substituted iron pnictides using an extended real-space Green's function method combined with density functional ca…
Disorder-Driven Superconductor-Insulator Transition in d-Wave Superconducting Ultrathin Films
Long He, Jian Sun, Yun Song
We study the superconductor-insulator transition (SIT) in -wave superconducting ultrathin films. By means of the kernel polynomial method, the Bogoliubov-de Gennes equations are…
Stable all nitrogen metallic salt at terapascal pressures
Jian Sun, Miguel Martinez-Canales, Dennis D. Klug +2
The phase diagram and equation of state of dense nitrogen are of interest in understanding the fundamental physics and chemistry under extreme conditions, including planetary proce…
Persistence and eventual demise of oxygen molecules at terapascal pressures
Jian Sun, Miguel Martinez-Canales, Dennis D. Klug +2
Computational searches for structures of solid oxygen under pressures in the multi TPa range have been carried out using density-functional-theory methods. We find that molecular o…
