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…

Radiant Field Theory: A Transport Approach to Shaped Wave Transmission through Disordered Media
David Gaspard, Arthur Goetschy
We present a field-theoretic framework to characterize the distribution of transmission eigenvalues for coherent wave propagation through disordered media. The central outcome is a…

Transmission eigenvalue distribution in disordered media from radiant field theory
David Gaspard, Arthur Goetschy
We develop a field-theoretic framework, called radiant field theory, to calculate the distribution of transmission eigenvalues for coherent wave propagation in disordered media. At…
