Spin-charge separation in the triangular-lattice Hofstadter-Hubbard model
Yuntian Gu, Hui Yang, Zhehao Dai +1
Recent experiments in moiré materials have enabled the realization of a variety of exotic quantum phases. In this context, the Hofstadter-Hubbard model has been proposed as a possi…
Magnetism and superconductivity in bilayer nickelate
Hui Yang, Ya-Hui Zhang
The discovery of high-temperature superconductivity in bilayer nickelate LaNiO necessitates a minimal theoretical model that unifies the superconducting phase wit…
Doping a spin-one Mott insulator: possible application to bilayer nickelate
Hanbit Oh, Hui Yang, Ya-Hui Zhang
In this article, we review some recent theoretical developments on potential high-temperature superconductors and unconventional metallic states that can arise from doping a spin-o…
High-temperature superconductivity from kinetic energy
Hanbit Oh, Hui Yang, Ya-Hui Zhang
Superconductivity is usually assumed to arise from attractive interaction. In this work we show that strong pairing is possible soley from kinetic energy even without a net attract…
Strong pairing and symmetric pseudogap metal in double Kondo lattice model: from nickelate superconductor to tetralayer optical lattice
Hui Yang, Hanbit Oh, Ya-Hui Zhang
In this work, we propose and study a double Kondo lattice model which hosts robust superconductivity. The system consists of two identical Kondo lattice model, each with Kondo coup…
Deconfined Fermi liquid to Fermi liquid transition and superconducting instability
Xiaofan Wu, Hui Yang, Ya-Hui Zhang
Deconfined quantum critical points (DQCP) have attracted lots of attentions in the past decades, but were mainly restricted to incompressible phases. On the other hand, various exp…
