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

This review presents the state of the art in strain and ripple-induced effects on the electronic
and optical properties of graphene. It starts by providing the crystallographic description of …

The basic aspects of electrons in graphene (two-dimensional graphite) exposed to a strong
perpendicular magnetic field are reviewed. One of its most salient features is the relativistic …

We develop a method to predict the existence of edge states in graphene ribbons for a large
class of boundaries. This approach is based on the bulk-edge correspondence between the …

Inspired by the great development of graphene, more and more research has been
conducted to seek new two-dimensional (2D) materials with Dirac cones. Although 2D Dirac …

Semiconductor devices rely on the charge and spin of electrons, but there is another
electronic degree of freedom called pseudospin in a two-level quantum system such as a …

The transport phenomena of zero-gap conductors are one of the central subjects in
condensed matter physics. α-(BEDT-TTF) 2I3 [BEDT-TTF= bis (ethylenedithio) …

We investigate the effect of an in-plane ac electric field coupled to electrons in the
honeycomb lattice and show that it can be used to manipulate the Dirac points of the …

Recently, quantum Hall state analogs in classical mechanics attract much attention from
topological points of view. Topology is not only for mathematicians but also quite useful in a …

By means of a microwave tight-binding analogue experiment of a graphenelike lattice, we
observe a topological transition between a phase with a pointlike band gap characteristic of …
