Pentagonal nanowires from topological crystalline insulators: a platform for intrinsic core-shell nanowires and higher-order topology
Ghulam Hussain, Giuseppe Cuono, Piotr Dziawa +12
We report on the experimental realization of Pb1-xSnxTe pentagonal nanowires (NWs) with [110] orientation using molecular beam epitaxy techniques. Using first-principles calculatio…
Topology of chalcogen chains
Adam Kłosiński, Wojciech Brzezicki, Alexander Lau +4
We investigate the topological properties of the helical atomic chains occurring in elemental selenium and tellurium. We postulate a realistic model that includes spin-orbit intera…
Engineering axion insulator phase in superlattices with inversion symmetry breaking
Rajibul Islam, Sougata Mardanya, Alexander Lau +6
We study theoretically the interplay between magnetism and topology in three-dimensional HgTe/MnTe superlattices stacked along the (001) axis. Our results show the evolution of the…
Topological states in superlattices of HgTe-class materials for engineering three-dimensional flat bands
Rajibul Islam, Barun Ghosh, Giuseppe Cuono +7
In search of materials with three-dimensional flat band dispersions, using {\em ab-initio} computations, we investigate how topological phases evolve as a function of hydrostatic p…
