M23: Inverse Wave Propagation Problems without Phase Information

This minisymposium is devoted to recent developments in phaseless inverse problems arising in quantum mechanics, optics and related areas. In these problems it is supposed that only the absolute value of fields can be measured directly in an experiment. In quantum mechanics this limitation is related to the probabilistic interpretation of wave function which goes back to Max Born (1926). Similarly, in optics most measurement techniques can only provide information on the amplitude of time-harmonic electromagnetic waves but not on their phase.

The aim of this minisymposium is to provide an overview on the state-of-the-art of this active field of research and to discuss the recent developments on the theoretical, algorithmic and experimental side. Experienced and young researchers will enjoy the possibility of sharing ideas and finding new collaborators.
