Research with Neutrons and Muons (NUM)

The NUM division performs world-class research with neutrons and muons to explore and understand matter and materials. The NUM division operates and develops the Swiss Spallation Neutron Source SINQ, the Ultra-cold Neutron Source UCN, the Swiss Muon Source SμS and the facilities for particle physics at the Paul Scherrer Institute and is one of the five PSI research divisions.

A theory for the gapless field-induced quantum spin-liquid phase of α−RuCl3

The material α−RuCl3 continues to garner attention as the current poster child for realising the Kitaev model. New work places recent experimental observations on a solid theoretical footing, and concludes that the physics of α−RuCl3 is not dominated by Kitaev interactions.

Spin ice goes quantum

Numerous intriguing behaviours have been observed already in magnetic materials known as spin ices. But now for the first time direct manifestations of quantum mechanical effects have been seen in such a system.
