Exact solutions of the inhomogeneous nonlinear Schrödinger equation through supersymmetric potentials
David J. Fernández C., O. Pavón-Torres
By employing supersymmetric quantum mechanics, we present a general algorithm to construct supersymmetric partner potentials and hence derive exact stationary solutions of the inho…

Confluent supersymmetric algorithm for bilayer graphene
Jonathan de la Cruz-Hernandez, David J. Fernández C.
External magnetic field profiles leading to equidistant and partially equidistant bilayer graphene spectra within the tight-binding model are obtained. This is achieved by implemen…

Bilayer graphene in periodic and quasiperiodic magnetic superlattices
David J. Fernández C., O. Pavón-Torres
Starting from the effective Hamiltonian arising from the tight binding model, we study the behaviour of low-lying excitations for bilayer graphene placed in periodic external magne…
