Superconductivity in three-dimensional interacting doped topological insulators
Andras L. Szabo, Bitan Roy
Three-dimensional doped Dirac insulators foster simply connected (in both topological and trivial regimes) and annular (deep inside the topological regime) Fermi surfaces (FSs) in…
Quantized thermal and spin transports of dirty planar topological superconductors
Sanjib Kumar Das, Bitan Roy
Nontrivial bulk topological invariants of quantum materials can leave their signatures on charge, thermal and spin transports. In two dimensions, their imprints can be experimental…
Hybrid symmetry class topological insulators
Sanjib Kumar Das, Bitan Roy
Traditional topological materials belong to different Altland-Zirnbauer symmetry classes (AZSCs) depending on their non-spatial symmetries. Here we introduce the notion of hybrid s…
Emergent metallicity at the grain boundaries of higher-order topological insulators
Daniel J. Salib, Vladimir Juričić, Bitan Roy
Topological lattice defects, such as dislocations and grain boundaries (GBs), are ubiquitously present in the bulk of quantum materials and externally tunable in metamaterials. In…
Dispersive nodal fermions along grain boundaries in Floquet topological crystals
Daniel J. Salib, Bitan Roy
Driven quantum materials often feature emergent topology, otherwise absent in static crystals. Dynamic bulk-boundary correspondence, encoded by nondissipative gapless modes residin…
Transport in strained graphene: Interplay of Abelian and axial magnetic fields
Aqeel Ahmed, Sanjib Kumar Das, Bitan Roy
Immersed in external magnetic fields (), buckled graphene constitutes an ideal tabletop setup, manifesting a confluence of time-reversal symmetry () breaking Abeli…
