Coherent states for graphene under the interaction of crossed electric and magnetic fields
Miguel Castillo-Celeita, Erik Díaz-Bautista, Maurice Oliva-Leyva
We construct the coherent states for charge carriers in a graphene layer immersed in crossed external electric and magnetic fields. For that purpose, we solve the Dirac-Weyl equati…

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…
