Transition between one- and two-dimensional topology in a Chern insulator of finite width
Frode Balling-Ansø, Adipta Pal, Ashley M. Cook +1
Topology in quantum systems is typically considered in infinite crystals in one, two, or higher integer dimensions. Here, we show that one can continuously transform a system betwe…

Multiplicative Chern insulator
Archi Banerjee, Ashley M. Cook
We study multiplicative Chern insulators (MCIs) as canonical examples of multiplicative topological phases of matter. Constructing the MCI Bloch Hamiltonian as a symmetry-protected…
