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 analysis of the electronic properties of strained or lattice deformed graphene combines
ideas from classical condensed matter physics, soft matter, and geometrical aspects of …

The Fermi velocity, v F, is one of the key concepts in the study of a material, as it bears
information on a variety of fundamental properties. Upon increasing demand on the device …

The Dirac cone on a surface of a topological insulator shows linear dispersion analogous to
optics and its velocity depends on materials. We consider a junction of two topological …

Pseudorelativistic Dirac quasiparticles have emerged in a plethora of artificial graphene
systems that mimic the underlying honeycomb symmetry of graphene. However, it is …

The conformal invariance of the low energy limit theory governing the electronic properties
of graphene is explored. In particular, it is noted that the massless Dirac theory in point …

We consider the effect of uniaxial strain on ballistic transport in graphene, across single and
multiple tunneling barriers. Specifically, we show that applied strain not only shifts the …

The electronic structure of a single-layer graphene with a periodic Fermi velocity modulation
is investigated by using an effective Dirac-like Hamiltonian. In a gapless graphene or in a …

We demonstrate that single-layer graphene in the presence of a metal gate displays a
gapless collective (plasmon) mode that has a linear dispersion at long wavelengths. We …

Searching for new states of matter and unusual quasi-particles in emerging materials and
especially low-dimensional systems is one of the major trends in contemporary condensed …
