Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

Graphene is a rapidly rising star on the horizon of materials science and condensed-matter
physics. This strictly two-dimensional material exhibits exceptionally high crystal and …

This article reviews the basic theoretical aspects of graphene, a one-atom-thick allotrope of
carbon, with unusual two-dimensional Dirac-like electronic excitations. The Dirac electrons …

A broad review of fundamental electronic properties of two-dimensional graphene with the
emphasis on density and temperature-dependent carrier transport in doped or gated …

We propose a simple realization of the three-dimensional (3D) Weyl semimetal phase,
utilizing a multilayer structure, composed of identical thin films of a magnetically doped 3D …

We analyze pairing of fermions in two dimensions for fully gapped cases with broken parity
(P) and time reversal (T), especially cases in which the gap function is an orbital angular …

We systematically study topological phases of insulators and superconductors (or
superfluids) in three spatial dimensions. We find that there exist three-dimensional (3D) …

Carbon is one of the most intriguing elements in the Periodic Table. It forms many allotropes,
some known from ancient times (diamond and graphite) and some discovered 10-20 years …

We present a study of “nodal-semimetal” phases in which nondegenerate conduction and
valence bands touch at points (the “Weyl semimetal”) or lines (the “line-node semimetal”) in …

The physics of Anderson transitions between localized and metallic phases in disordered
systems is reviewed. The term “Anderson transition” is understood in a broad sense …
