Motivated by current interest in quantum confinement potentials, especially with respect to
the Stark spectroscopy of new types of quantum wells, we examine several novel one …

A new systematic approach to the construction of approximate solutions to a class of
nonlinear singularly perturbed feedback control systems using the boundary layer functions …

In this paper we propose a reliable algorithm to develop approximate analytical solutions of
a class of nonlinear third order singularly perturbed boundary-value problems exhibiting …

The mathematical modeling of low dimensional quantum systems is discussed in this
chapter. In particular, the use of generalized functions in such modeling is illustrated in some …

We examine the one-dimensional quantum dynamics of a Schroedinger particle in a
potential represented by a generalized function of the form $ U (x)=-\alpha\delta (x)+\beta d …
