Generating particle-like scattering states in wave transport — •Stefan Rotter, Philipp Ambichl, and Florian Libisch — Institute for Theoretical Physics, TU Vienna, Austria

We introduce a class of scattering states which display trajectory-like wave function patterns in coherent transport through complex scatterers. These deterministic scattering states feature the dual property of being eigenstates to the Wigner-Smith time-delay matrix and to the transmission matrix with classical transmission eigenvalues close to 0 or 1. An operational protocol for generating these states based on the scattering matrix is put forward and successfully tested numerically for regular, chaotic and disordered scattering systems. These results pave the way for the experimental realization of particle-like wave fronts in transport through complex media with possible applications like secure and low-power communication.
