Relations between Transfer and Scattering Matrices in the presence of Hyperbolic Channels
Christian Sadel
We consider a cable described by a discrete, space-homogeneous, quasi one-dimensional Schrödinger operator . We study the scattering by a finite disordered piece (the scattere…
Ballistic Behavior for Random Schrödinger Operators on the Bethe Strip
Abel Klein, Christian Sadel
The Bethe Strip of width is the cartesian product $\B\times\{1,...,m\}$, where $\B$ is the Bethe lattice (Cayley tree). We consider Anderson-like Hamiltonians $H_λ=\frac12 Δ\ot…
Dissipative dynamics in semiconductors at low temperature
George Androulakis, Jean Bellissard, Christian Sadel
A mathematical model is introduced which describes the dissipation of electrons in lightly doped semi-conductors. The dissipation operator is proved to be densely defined and posit…
Absolutely Continuous Spectrum for Random Schroedinger Operators on the Bethe Strip
Abel Klein, Christian Sadel
The Bethe Strip of width is the cartesian product $\B\times\{1,...,m\}$, where $\B$ is the Bethe lattice (Cayley tree). We prove that Anderson models on the Bethe strip have "e…
