Exact Stiffness and Dynamical Responses from Fock-Space Fragmentation
Jonah Herzog-Arbeitman, Eslam Khalaf, Zhaoyu Han
Exactly solvable quantum many-body models are rare, and even when their spectra are algebraically organized, dynamical responses generally remain difficult to obtain because they p…
A quantum geometric mechanism for chiral domain wall metastability: Application to twisted transition-metal dichalcogenides
Nisarg Chadha, Qiang Gao, Eslam Khalaf +1
Band topology can have an imprint on the excitations of a ferromagnet. A known example is quantum Hall ferromagnets and their lattice analogs; when both flavors have the same Chern…
Observation of metastable chiral domain walls in a topological magnet
Richen Xiong, Chenxin Qin, Zhaoyu Han +17
The interplay between topology and correlation can give rise to exotic collective excitations. The integer and fractional quantum anomalous Hall (QAH) magnets recently discovered i…
Single-component twisted orthogonal metal in an -anyon fluid
Zhaoyu Han, Ashvin Vishwanath, Eslam Khalaf
We propose an unconventional metallic phase emerging upon doping the Laughlin Fractional Chern insulator, which can serve as a parent state to anyon superconductivity with ar…
Self-doped Crystal from Preempted Band-inversion Transitions
Jiechao Feng, Zhaoyu Han, Michael P. Zaletel +1
Recent experiments in rhombohedral graphene find evidence for a "self-doped" Wigner crystal (SDC) in which a slightly incommensurate Wigner crystal (WC) coexists with a small Fermi…
Exact models of chiral flat-band superconductors
Zhaoyu Han, Jonah Herzog-Arbeitman, Qiang Gao +1
Recent experiments have reported the surprising observation of superconductivity in flavor polarized, nearly flat bands (FBs) of rhombohedral graphene. Motivated by these findings,…
Anyon superfluidity of excitons in quantum Hall bilayers
Zhaoyu Han, Taige Wang, Zhihuan Dong +2
The charged anyons of a fractional quantum Hall fluid are necessarily dispersionless due to the continuous magnetic translation symmetry. Neutral anyons, however, can disperse, res…
Bootstrapping Flat-band Superconductors: Rigorous Lower Bounds on Superfluid Stiffness
Qiang Gao, Zhaoyu Han, Eslam Khalaf
The superfluid stiffness fundamentally constrains the transition temperature of superconductors, especially in the strongly coupled regime. However, accurately determining this inh…
Anyon superconductivity and plateau transitions in doped fractional quantum anomalous Hall insulators
Pavel A. Nosov, Zhaoyu Han, Eslam Khalaf
Recent experiments reported evidence of superconductivity and re-entrant integer quantum anomalous Hall (RIQAH) insulator upon doping the fractional quantum anomalous H…
Pair-density-wave and superconductivity in a strongly coupled, lightly doped Kondo insulator
Fangze Liu, Zhaoyu Han
We investigate the large Kondo coupling limit of the Kondo-Heisenberg model on one- and two-dimensional lattices. Focusing on the possible superconducting states when slightly dopi…
