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
The paper proposes a new metallic phase that appears when a 1/3 fractional Chern insulator is doped, featuring a Fermi surface of emergent charge‑e/3 fermions coupled to a twisted…
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…
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…
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…
