In this work we calculate the exact Green's function for arbitrary rectangular potentials.
Specifically we focus on Green's function for rectangular quantum wells enlarging the …

We study the effects of dissipation on electron transport in a semiconductor superlattice with
an applied bias voltage and a magnetic field that is tilted relative to the superlattice axis. In …

The dynamics of chaotic billiards is significantly influenced by coexisting regions of regular
motion. Here we investigate the prevalence of a different fundamental structure, which is …

We introduce a very general approximation to the quantum propagator that is based on the
assumption that the most important contributions to the complex semiclassical propagator …

Summary The Quantum Cascade Laser (QCL) concept is extremely versatile and is now
considered to be ready for take‐off in a large variety of technological applications covering …

The distribution of tunneling rates in the presence of classical chaos is derived. We use
classical information about tunneling trajectories plus random matrix theory arguments …

We show how quantum mechanical barrier reflection and transmission coefficients Script R
and Script T can be obtained from asymptotic Green functions. We exemplify our results by …

We develop a semiclassical theory of Coulomb blockade peak heights in chaotic quantum
dots. Using Berry's conjecture, we calculate peak height distributions and correlation …

From the poles of a generalized semiclassical Green's function we derive expressions for
the eigenvalues of 1D multiple well potentials. In the case of asymmetric and symmetric …

We develop a semiclassical theory of Coulomb blockade peak heights in quantum dots and
show that the dynamics in the dot leads to a large modulation of the peak height. The …
