We present a detailed study of a generalised one-dimensional Kronig–Penney model using
δ-δ'δ-δ′ potentials. We analyse the band structure and the density of states in two …

We report on the electronic structure, density of states and transmission properties of the
periodic one-dimensional tight-binding (TB) lattice with a single orbital per site and nearest …

We present new symbolic-numeric algorithms for solving the Schrödinger equation
describing the scattering problem and resonance states. The boundary-value problems are …

Tunneling times in absorptive media, described by complex potentials, are investigated. A
general expression relating relevant tunneling times is extended by introducing a new term …

We study the electronic properties of a one-dimensional disordered chain made up of
Pöschl-Teller potentials. The features of the whole spectrum of the random chain in the …

In this work we describe, compile and generalize a set of tools that can be used to analyse
the electronic properties (distribution of states, nature of states, etc) of one-dimensional …

The effect of a continuous model of correlations upon one-dimensional finite disordered
quantum wires modeled by an array of delta-potentials, is analyzed. Although the model …

Tunneling of electrons through a barrier with complex potential is investigated. We focus on
two cases, symmetric double rectangular barrier and double delta potential barrier, and give …

We propose a simple model of two coupled mesoscopic rings threaded by magnetic flux
which mimics a device for electron transmission in a controlled fashion. Within a tight …

The dynamics of absorption is analyzed by using an exactly solvable model that deals with
an analytical solution to Schrödinger's equation for cutoff initial plane waves incident on a …
