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.
