In closed systems, thermodynamics foresees that all evolutions lead to an equilibrium state. However this notion was recently challenged by the demonstration of many-body localisation, which arises among the interplay of disorder-induced localisation and many-body interactions. We ask the question: can a localised phase exist in an open, interacting, driven-dissipative system. In collaboration with an experimental group from EPFL we demonstrate the localisation of microcavity polaritons, as witnessed by the inverse participation-ratio.
