Global phase diagram of two-dimensional dirty hyperbolic Dirac liquids

Christopher A. Leong, Daniel J. Salib, Bitan Roy

Within the framework of the canonical nearest-neighbor tight-binding model for spinless fermions, a family of two-dimensional bipartite hyperbolic lattices hosts massless Diraclike…

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…

Topological insulators on fractal lattices: A general principle of construction

Daniel J. Salib, Aiden J. Mains, Bitan Roy

Fractal lattices, featuring the self-similarity symmetry, are often geometric descents of parent crystals, possessing all their discrete symmetries (such as rotations and reflectio…

Model non-Hermitian topological operators without skin effect: A general principle of construction

Daniel J. Salib, Sanjib Kumar Das, Bitan Roy

We propose a general principle of constructing non-Hermitian (NH) operators for insulating and gapless topological phases in any dimension () that over an extended NH parameter…

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…
