Berry-Landau Fermi-liquid theory: transport in presence of quantum geometry
Shuai A. Chen, Roderich Moessner
Landau Fermi-liquid theory characterizes interacting metals through quasiparticles and their residual interactions. It is a challenge to incorporate non-trivial quantum geometry --…
Kinetic kagome magnetism: from self-trapping RVB polarons to semiclassical correlations
Yufei Pei, Shuai A. Chen, Claudio Castelnovo +1
To gain deeper insight into the role of hole kinetics in determining magnetism in highly frustrated doped Mott insulators, we consider the single-hole counter-Nagaoka problem on th…
Generalized Peierls substitution for Wannier obstructions: response to disorder and interactions
Shuai A. Chen, Roderich Moessner, Tai Kai Ng
We study the interplay between quantum geometry, interactions, and external fields in complex band systems. When Wannier obstructions preclude a description based solely on atomic-…
Geometric Frustration Assisted Kinetic Ferromagnetism in Doped Mott Insulators
Qianqian Chen, Shuai A. Chen, Zheng Zhu
Understanding ferromagnetism mechanism in doped Mott insulators on frustrated lattices remains challenging at intermediate coupling and finite doping. Here, we study the itinerant…
