Emergent fractals in dirty topological crystals
Daniel J. Salib, Bitan Roy
Non-trivial geometry of electronic Bloch states gives rise to topological insulators which are robust against sufficiently weak randomness inevitably present in any quantum materia…
Superconductivity in doped planar Dirac insulators: A renormalization group study
Sk Asrap Murshed, Sanjib Kumar Das, Bitan Roy
From a leading-order unbiased renormalization group analysis we here showcase the emergence of superconductivity (including the topological ones) from purely repulsive electron-ele…
From local spin nematicity to altermagnets: Footprints of band topology
Sanjib Kumar Das, Bitan Roy
Altermagnets are crystallographic rotational symmetry breaking spin-ordered states, possessing a net zero magnetization despite manifesting Kramer's non-degenerate bands. Here, we…
Non-unitary time dynamics of topological modes in open planar quantum systems
Saakshi Porwal, Bitan Roy
Nontrivial topological invariant of bulk electronic wavefunctions in two-dimensional quantum crystals leaves its footprints on the edge, dislocation, and corner modes. Here we inve…
