Ray-segment scars in the random wave model — •Jakob Lindermeir, Jan Robert Schmidt, and Roland Ketzmerick — TU Dresden, Institute of Theoretical Physics, Dresden, Germany

A new type of scars along ray segments, unrelated to periodic-orbit scars, was recently observed in optical microcavities [1] and in the 3-disk scattering system. We introduce a method for their numerical analysis and apply it, as a first step, to the random wave model. This method involves calculating a new representation of the wave function that distinctly highlights scars. Subsequent steps enable the determination of length, width, and wavenumber of these scars. We compare the result of the numerical analysis to analytical predictions.
