Exotic ground states in high magnetic fields — •Andreas Läuchli — IRRMA, Ecole Polytechnique Fédérale de Lausanne, Switzerland

Over the last few years it has been discovered that quantum magnets in strong magnetic fields can host a variety of long-sought exotic phases. In this talk we review recent theoretical efforts revealing magnetization plateaux with complex structures, supersolid phases sustaining simultaneous longitudinal and transverse magnetic order, as well as spin nematic phases, which spontaneously break spin rotational symmetry in the absence of an ordered moment. We discuss the experimental signatures of these phases and point out materials which could possibly display such exciting behavior.
