Exactly solvable lattice models for interacting electronic insulators in two dimensions

Qing-Rui Wang, Yang Qi, Chen Fang +2

In the past decade, tremendous efforts have been made towards understanding fermionic symmetry protected topological (FSPT) phases in interacting systems. Nevertheless, for systems…

Robustness of Antiferromagnetism in the Su-Schrieffer-Heeger-Hubbard model

Xun Cai, Zi-Xiang Li, Hong Yao

We recently unveiled that antiferromagnetism (AFM) order can be dominantly induced by the bond Su-Schrieffer-Heeger (SSH) electron-phonon coupling (EPC), which is beyond the conven…

A unified theory of ferromagnetic quantum phase transitions in heavy fermion metals

Jiangfan Wang, Yi-feng Yang

Motivated by the recent discovery of a continuous ferromagnetic quantum phase transition in CeRhGe and its distinction from other U-based heavy fermion metals such as UGe$_…
