Directionality emergence and localization in a quantum random Lorentz gas
Baptiste Lorent, Jean-Marc Sparenberg, David Gaspard
The propagation of a spherical wave through a two-dimensional random Lorentz gas composed of small fixed scatterers is studied. Inspired by the Mott problem (how an initially isotr…

Effective-medium approach to the resonance distribution of wave scattering in a random point field
David Gaspard, Jean-Marc Sparenberg
In a previous paper [Phys. Rev. A 105, 042205 (2022)], the distribution of resonance poles in the complex plane of the wavenumber associated to the multiple scattering of a qua…
