Abstract Bismuth selenide (Bi 2 Se 3 ) epitaxial films were grown at different substrate temperatures ( T s ) by molecular beam epitaxy. In the optimization of T s , a Bi 2 Se 3 film with the smallest root mean square roughness (Rq) and the lowest electron den…

A data-driven approach to calculating tight-binding models for discrete coupled-mode systems is presented. In particular, spectral and topological data are used to build an appropriate discrete model that accurately replicates these properties. This work is mo…

Abstract Since the advent of topological insulators hosting Dirac surface states, efforts have been made to gap these states in a controllable way. A new route to accomplish this was opened up by the discovery of topological crystalline insulators where the to…

Abstract Wepropose a scheme realizing topological insulators and quantized pumps for magnon excitations, based on strongly-interacting two-component ultracold atoms trapped in optical superlattices. Specifically, we show how to engineer the Su–Schrieffer–Heege…

We show that topological defects in quadrupole insulators do not host quantized fractional charges, contrary to what their Wannier representation indicates. In particular, we test the charge quantization hypothesis based on the Wannier representation of a disc…

The magneto-transport properties of Bi2Se3–ySy were investigated. Magnetoresistance (MR) decreases with an increase in the S content, and finally, for 7% (i.e., y = 0.21) S doping, the magnetoresistance becomes negative. This negative MR is unusual as it is ob…

By introducing a new type of strained lattice, one dimensional arm-distorted ribbons, we demonstrate the possibility of opening a bandgap from the originally gapless graphene nanoribbons in the ℤ2 topological class. Typically, a gap opens up due to time-revers…
