Hofstadter Butterflies in Topological Insulators
Larry Li, Marcin Abram, Abhinav Prem +1
In this chapter, we investigate the energy spectra as well as the bulk and surface states in a two-dimensional system composed of a coupled stack of one-dimensional dimerized chain…

Dislocation Non-Hermitian Skin Effect
Frank Schindler, Abhinav Prem
We demonstrate that crystal defects can act as a probe of intrinsic non-Hermitian topology. In particular, in point-gapped systems with periodic boundary conditions, a pair of disl…

Topological states on fractal lattices
Shriya Pai, Abhinav Prem
We investigate the fate of topological states on fractal lattices. Focusing on a spinless chiral p-wave paired superconductor, we find that this model supports two qualitatively di…
