Neutrons Verify New Quantum State

An international research team has proved the existence of spin-spirals in a quantum liquid.

An international research team has proved the existence of spin-spirals in a quantum liquid. They emerge at low temperatures from the magnetic moments ("spins") of manganese scandium thiospinel single crystals (MnSc2S4). Neighbouring spins fluctuate here collectively as spirals, but when spatial distances are involved, they do not take on any particular order, just as water molecules will only form structures with neighbouring water molecules.

Nobel Prize in Physics for theoretical discoveries of topological phase transitions and topological phases of matter: neutron experiments confirm

David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz

The award-winning work of David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz served as the theoretical underpinning of the science of quantum topology. It is being recognised now largely due to validation provided by experiments performed at neutron sources over the last 25 years. That research has led to advances in the understanding of fields as diverse as superconductivity, lasers, superfluids and thin magnetic films. [more] [archive]
