Coulomb distortion of relativistic electrons in the nuclear electrostatic field
Andreas Aste, Cyrill von Arx, Dirk Trautmann
Continuum states of the Dirac equation are calculated numerically for the electrostatic field generated by the charge distribution of an atomic nucleus. The behavior of the wave fu…
Holographic entropy bound from gravitational Fock space truncation
Andreas Aste
A simplified derivation of Yurtsever's result, which states that the entropy of a truncated bosonic Fock space is given by a holographic bound when the energy of the Fock states is…
Improved effective momentum approximation for quasielastic (e,e') scattering off highly charged nuclei
Andreas Aste, Juerg Jourdan
We address the problem of including Coulomb distortion effects in inclusive quasielastic (e,e') reactions using an improved version of the effective momentum approximation. Argumen…
Full Hydrodynamic Simulation of GaAs MESFETs
Andreas Aste, Ruediger Vahldieck, Marcel Rohner
A finite difference upwind discretization scheme in two dimensions is presented in detail for the transient simulation of the highly coupled non-linear partial differential equatio…
Time-domain simulation of the full hydrodynamic model
A. Aste, R. Vahldieck
A simple upwind discretization of the highly coupled non-linear differential equations which define the hydrodynamic model for semiconductors is given in full detail. The hydrodyna…
Coulomb Corrections for Coherent Electroproduction of Vector Mesons: Eikonal Approximation
A. Aste, K. Hencken, D. Trautmann
Virtual radiative corrections due to the long range Coulomb forces of heavy nuclei with charge Z may lead to sizeable corrections to the Born cross section usually used for lepton-…
