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…

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…
