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 …

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 …

One of the intriguing properties characteristic to three-dimensional topological materials is
the topological magnetoelectric phenomena arising from a topological term called the θ …

We consider a two-dimensional electron gas with strong spin-orbit coupling contacted by
two superconducting leads, forming a Josephson junction. We show that in the presence of …

Understanding Dirac-like fermions has become an imperative in modern condensed matter
sciences: All across the research frontier, from graphene to high T c superconductors to the …

Much like the world described in Abbott's Flatland, graphene is a two-dimensional object.
And, as “Flatland” is “a romance of many dimensions,” graphene is much more than just a …

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 …

Topology of electron wavefunctions was first introduced to characterize the quantum Hall
states in two dimensions discovered in 1980 (ref.). Over the past decade, it has been …

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

The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are
exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as …
