Theory for strained graphene beyond the Cauchy-Born rule
Maurice Oliva-Leyva, Chumin Wang
The low-energy electronic properties of strained graphene are usually obtained by transforming the bond vectors according to the Cauchy-Born rule. In this work, we derive a new eff…
Resonant thermoelectric transport in atomic chains with Fano defects
J. Eduardo González, Vicenta Sánchez, Chumin Wang
Atomic clusters attached to a low-dimensional system, called Fano defects, produce rich wave interferences. In this work, we analytically found an enhanced thermoelectric figure-of…
Fingerprints of a position-dependent Fermi velocity on scanning tunnelling spectra of strained graphene
M. Oliva-Leyva, J. E. Barrios-Vargas, Chumin Wang
Nonuniform strain in graphene induces a position dependence of the Fermi velocity, as recently demonstrated by scanning tunnelling spectroscopy experiments. In this work, we study…
Magneto-optical conductivity of anisotropic two-dimensional Dirac-Weyl materials
Maurice Oliva-Leyva, Chumin Wang
In the presence of an external magnetic field, the optical response of two-dimensional materials, whose charge carriers behave as massless Dirac fermions with arbitrary anisotropic…
Low-energy theory for strained graphene: an approach up to second-order in the strain tensor
Maurice Oliva-Leyva, Chumin Wang
An analytical study of low-energy electronic excited states in an uniformly strained graphene is carried out up to second-order in the strain tensor. We report an new effective Dir…
