Host: Yi Li Critical Filaments and Fractal-Mediated Superconductivity in Quasiperiodic Twisted Bilayer Graphene The electronic properties of quantum materials depend on the symmetry, topology, and spatial structure of electron wave functions. It was previously shown that superconductivity can be boosted by spatially rarified wave functions shaped by random or structured inhomogeneity. Recently, the twisting of […]

Title: “Topological Crystalline Markers for Rotational-Symmetric Insulators” Abstract: “Topological insulators are materials with unique properties, featuring gapless boundary modes despite having a gapped bulk. When translational symmetry is intact, their topologically non-trivial characteristics can be identified using momentum-space based topological invariants. Yet, challenges arise when bulk disorder and defects break translational symmetry, making momentum-space approaches […]
