Wigner vs. Smith: Time delays in anisotropic potentials — •Ulf Saalmann and Jan M Rost — Max-Planck-Institut für Physik komplexer Systeme, Dresden/Germany

Scattering properties and time delays for non-symmetric potentials are discussed paradigmatically in one dimension in comparison to symmetric ones. Only for the latter the Wigner and Smith time delays coincide. We further discuss the importance of the potential position and give a criterion how to identify a potential with intrinsic symmetry which behaves like an asymmetric one if it is merely offset from the scattering center.
