Abstract: The quantum liquid phases of 3He confined in random solids and sub-micron structures provide a unique system for studying the struggle between spontaneous symmetry breaking by a BCS condensate, and disorder originating from atomic-scale impurities to bulk and surface random potentials. This competition leads to a remarkable spectrum of phases exhibiting broken spin- and orbital rotation symmetries, as well as discrete space-time symmetries, that are not realized in pure liquid 3He. I will highlight theoretical ideas and understanding of the effects of disorder on unconventional BCS condensates that have emerged from studies of the superfluid phases of liquid 3He in random media and confined geometries.
