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…
Finite-size topological phases from semimetals
Adipta Pal, Ashley M. Cook
Topological semimetals are some of the topological phases of matter most intensely-studied experimentally. The Weyl semimetal phase, in particular, has garned tremendous, sustained…
Robust quantisation of circular photogalvanic effect in multiplicative topological semimetals
Adipta Pal, Dániel Varjas, Ashley M. Cook
Nonlinear response signatures are increasingly recognized as useful probes of condensed matter systems, in particular for characterisation of topologically non-trivial states. The…
Multiplicative topological semimetals
Adipta Pal, Joe H. Winter, Ashley M. Cook
Exhaustive study of topological semimetal phases of matter in equilibriated electonic systems and myriad extensions has built upon the foundations laid by earlier introduction and…
