Muon Spin Rotation/Relaxation Studies of Unconventional Superconductivity
Speaker(s): Graeme Luke
Abstract: Muon spin rotation/relaxation is a powerful technique for studying unconventional superconductors, whose order parameter doesn't have the same symmetry as its host material's crystal structure. I will describe our work on Sr2RuO4, UPt3, CuxBi2Se3 and other topical systems, some of which exhibit bro... read more

Quantum fluctuations in spin ice
Speaker(s): Graeme Luke
Abstract: Geometrical frustration in magnetic systems provides a rich playground to study the emergence of novel ground states. In systems where not all magnetic couplings can be simultaneously satisfied, conventional long range magnetic order is often precluded, or pushed to much lower emperature scales than... read more

Nature of Hidden Order in URu2Si2
Speaker(s): Graeme Luke
Abstract: URu2Si2 is a moderate heavy fermion system which undergoes two transitions with decreasing temperature. The lower transition (1.5K) is to a possibly unconventional superconducting state, whereas the nature of the upper transition (17.5K) is poorly understood. Large lambda-like anomalies are seen in ... read more
