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.

Superconducting muon spin depolarization rate for NbSe2

The multi-layered physics of layered superconductors

Muon spin rotation experiments provide unique microscopic insight into the superconductivity and magnetism of transition metal dichalcogenides — and reveal complex and unconventional patterns, hinting towards a common mechanism for and electronic origin of ‘unconventional’ superconductivity.

Pinning down the proximate ­Kitaev spin liquid

A study of the extended Kitaev model on the honeycomb lattice that factors in Kitaev, Heisenberg and off-diagonal symmetric interactions provides both a definitive answer on proximate Kitaev states and an essential guide to the physics of candidate Kitaev materials.

On the way to intelligent microrobots

Media Releases Matter and Material Materials Research

It is reminiscent of a paper bird made with the help of the Japanese folding art origami: a microrobot that uses the force of magnetic fields to move. In the future, such small machines could be used, for example, in medical operations.
