Two-dimensional topological quantum chemistry and catalog of topological materials

Two-dimensional (2D) topological materials host symmetry-protected, disorder-robust edge states central to quantum technologies. Yet they remain scarce compared with their 3D counterparts. We adapted the topological quantum chemistry formalism to layer groups and studied the band...

2D theoretically twistable material database

The study of twisted two-dimensional (2D) materials, in which twisting layers create moiré superlattices, has created opportunities for investigating topological phases and strongly correlated physics. The broader potential of a seemingly infinite set of twistable 2D materials re...

Entropy plateaus, combinatorial degeneracy, local moments, and heavy-fermion mass renormalization in magic-angle graphene

Abstract Heavy-fermion behavior, driven by the interaction-induced enhancement of electronic mass, underpins exotic states ranging from unconventional superconductivity to quantum criticality. Long restricted to complex three-dimensional f- electron compounds, these phenomena are...
