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…

Signatures of the quantum skyrmion Hall effect in the Bernevig-Hughes-Zhang model
Reyhan Ay, Adipta Pal, Ashley M. Cook
Given recent discovery of the quantum skyrmion Hall effect, we re-examine the related canonical Bernevig-Hughes-Zhang (BHZ) model for the quantum spin Hall insulator. Within the fr…
