The aim of this conference is to provide the opportunity for leading scientists and younger researchers to meet for discussions on the most recent developments in the field of quantum simulation with open quantum systems. Topics include but are not limited to cavity quantum electrodynamics, emergent dissipative non-equilibrium phenomena, dissipation engineering, dynamical phase transitions, many-body quantum information, and, more general, cavity-assisted manipulation of materials. The conference is open to scientists world-wide, whether from academia or industry, but limited a maximum attendance of around 80 participants.
