The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

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 …

This is an introductory review of the physics of topological quantum matter with cold atoms.
Topological quantum phases, originally discovered and investigated in condensed matter …

We investigate the occurrence of n-fold exceptional points (EPs) in non-Hermitian systems,
and show that they are stable in n-1 dimensions in the presence of antiunitary symmetries …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

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

Dirac points are central to many phenomena in condensed-matter physics, from massless
electrons in graphene to the emergence of conducting edge states in topological insulators …

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 …

An introduction to the transport properties of graphene combining experimental results and
theoretical analysis is presented. In the theoretical description simple intuitive models are …

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 …
