Kane-Mele with a twist: Quasicrystalline higher-order topological insulators with fractional mass kinks
Stephen Spurrier, Nigel R. Cooper
We establish an analytic low-energy theory describing higher-order topological insulator (HOTI) phases in quasicrystalline systems. We apply this to a model consisting of two stack…

Theory of quantum oscillations in quasicrystals: Quantizing spiral Fermi surfaces
Stephen Spurrier, Nigel R. Cooper
We show that electronic materials with disallowed rotational symmetries that enforce quasiperiodic order can exhibit quantum oscillations and that these are generically associated…

Semiclassical Dynamics, Berry Curvature and Spiral Holonomy in Optical Quasicrystals
Stephen Spurrier, Nigel R. Cooper
We describe the theory of the dynamics of atoms in two-dimensional quasicrystalline optical lattices. We focus on a regime of shallow lattice depths under which the applied force c…
