The major breakthroughs in understanding of topological materials over the past decade
were all triggered by the discovery of the Z2-type topological insulator—a type of material …

We develop a systematic approach for constructing symmetry-based indicators of a
topological classification for superconducting systems. The topological invariants …

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 …

Transition metal dichalcogenides exhibit many fascinating properties including
superconductivity, magnetic orders, and charge density wave. The combination of these …

We consider weak topological insulators with a twofold rotation symmetry around their “dark”
direction and show that these systems can be endowed with the topological crystalline …

Nonzero spin polarization occurs in nonmagnetic materials induced by spin-orbital coupling
when inversion symmetry is broken. Understanding the origin of spin polarization is …

Among the quantum materials that have recently gained interest are the topological
insulators, wherein symmetry-protected surface states cross in reciprocal space, and the …

A honeycomb layer of transition metal-centered bismuth cubes has attracted attention as
part of the weak topological insulator (TI) Bi14Rh3I9. The intermetallic layer itself is a two …

We propose a different route to time-reversal invariant Weyl semimetals by employing
multilayer heterostructures comprising ordinary “trivial” insulators and nontrivial insulators …

This book presents the observation and the control of spin-polarized electrons in Rashba
thin films and topological insulators, including the first observations of a weak topological …
