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 wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

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 …

The problem of electron-electron interactions in graphene is reviewed. Starting from the
screening of long-range interactions in these systems, the existence of an emerging Dirac …

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

In graphene, electron–electron interactions are expected to play a significant role, as the
screening length diverges at the charge neutrality point and the conventional Landau theory …

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 …

The physics of graphene is acting as a bridge between quantum field theory and condensed
matter physics due to the special quality of the graphene quasiparticles behaving as …

The conductance and thermoelectric power (TEP) of graphene is simultaneously measured
using a microfabricated heater and thermometer electrodes. The sign of the TEP changes …

The surface states of a topological insulator are described by an emergent relativistic
massless Dirac equation in 2+ 1 dimensions. In contrast with graphene, there is an odd …
