Emergent Phases in quantum magnets — •Markos Skoulatos¹, Christian Pfleiderer¹, and Astrid Schneidewind² — ¹Physik-Department, Technische Universitaet Muenchen, D-85748 Garching, Germany — ²Juelich Centre for Neutron Science (JCNS) at Heinz Maier-Leibnitz Zentrum (MLZ), Forschungszentrum Juelich GmbH, Garching, Germany

Quantum magnets exhibit exotic ground states and novel elementary excitations, complex correlations and generic quantum critical points. Phenomena like frustration, condensation and quantum disorder are at the very heart of this field. More interestingly, novel emergent behavior can arise as a result of interplay between different characters of the same system. Examples include spin and orbital interplay in Mott insulators or spin liquid and spin nematic phases arising due to frustration in very simple model systems. In the light of this, some new results will be briefly discussed.
