On the electron-polaron--electron-polaron scattering and Landau levels in pristine graphene-like quantum electrodynamics
W. B. De Lima, O. M. Del Cima, E. S. Miranda
The parity-preserving massless QED is proposed as a pristine graphene-like planar quantum electrodynamics model. The spectrum content, the degrees of freedom,…

On the two-dimensional Schrödinger operator with an attractive potential of the Bessel-Macdonald type
W. B. De Lima, O. M. Del Cima, D. H. T. Franco +1
We analyze the Schrödinger operator in two-dimensions with an attractive potential given by a Bessel-Macdonald function. This operator is derived in the non-relativistic approximat…
