The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

In this review, we discuss recent progress in the explorations of topological materials
beyond topological insulators; specifically, we focus on topological crystalline insulators and …

Three-dimensional topological (crystalline) insulators are materials with an insulating bulk
but conducting surface states that are topologically protected by time-reversal (or spatial) …

Three-dimensional topological crystalline insulators were recently predicted and observed
in the SnTe class of IV–VI semiconductors, which host metallic surface states protected by …

Topological crystalline insulators (TCIs) are new states of matter whose topological
distinction relies on the crystal symmetry of periodic solids. The first material realization of …

We theoretically predict that thin-film topological crystalline insulators can host various
quantum anomalous Hall phases when doped by ferromagnetically ordered dopants. Any …

Two-dimensional (2D) topological crystalline insulators (TCIs) were recently predicted in thin
films of the SnTe class of IV–VI semiconductors, which can host metallic edge states …

In the recently discovered topological crystalline insulators SnTe and Pb 1− x Sn x (Te, Se),
crystal symmetry and electronic topology intertwine to create topological surface states with …

Two-dimensional (2D) topological crystalline insulator, a new class where states are
protected by lattice symmetry instead of by time-reversal symmetry, is predicted in PbSe …

The newly discovered topological crystalline insulators feature a complex band structure
involving multiple Dirac cones,,,,,, and are potentially highly tunable by external electric field …
