Coherent states for dispersive pseudo-Landau-levels in strained honeycomb lattices
Erik Díaz-Bautista, Maurice Oliva-Leyva
Dirac fermions in graphene may experiment dispersive pseudo-Landau levels due to a homogeneous pseudomagnetic field and a position-dependent Fermi velocity induced by strain. In th…
Effective magnetic field induced by inhomogeneous Fermi velocity in strained honeycomb structures
M. Oliva-Leyva, J. E. Barrios-Vargas, G. Gonzalez de la Cruz
In addition to the known pseudomagnetic field, nonuniform strains independently induce a position-dependent Fermi velocity (PDFV) in graphene. Here we demonstrate that, due to the…
Unveiling optical in-plane anisotropy of 2D materials from oblique incidence of light
Maurice Oliva-Leyva, Gerardo Gonzalez de la Cruz
In this work, we present a theoretical study of the dispersion of linearly polarized light between two dielectric media separated by an anisotropic two-dimensional (2D) material un…
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…
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…
