Title: An explicit model for the adiabatic evolution of quantum observables
driven by 1D shape resonances.

Abstract: Our work is concerned with a linearized version of the
quantum transport problem where the Schršdinger-Poisson operator is
replaced by a non-autonomous Hamiltonian, slowly varying in time. We
consider an explicitly solvable system where a semiclassical island is
described by a flat potential barrier, while a time dependent delta
interaction is used as a model for a single quantum well. Introducing,
in addition to the complex deformation, a further modi...cation formed
by arti...cial interface conditions, we give a reduced equation for
the adiabatic evolution of the sheet density of charges accumulating
around the interaction point.
