Correct statement of a scattering problem for quantum charged scalar particles on the Reissner-Nordstr\"{o}m black holes
We study a correct statement of the scattering problem arising for quantum
charged scalar particles on the Reissner-Nordstr\"{o}m black holes when taking
into account the own electric field of black hole. The elements of the
corresponding S-matrix are explored in the form convenient to physical
applications and for applying numerical methods. Some further possible issues
are outlined.Comment: 12 pages, LaTeX with using the ijmpd1.sty file from the package of

Electrons scattering in the monolayer graphene with the short-range impurities
Scattering problem for electrons in monolayer graphene with short-range
perturbations of the types "local chemical potential" and "local gap" has been
solved. Zero gap and non-zero gap kinds of graphene are considered. The
determined S-matrix can be used for calculation of such observables as
conductance and optical absorption
