"Twists in quantum magnets"


David Alan Tennant , Spallation Neutron Source, Oak Ridge National Laboratory
[Host: Seunghun Lee]
ABSTRACT:

Neutrons provide the ability to look at quantum states of matter in unrivaled detail. Using quantum magnets in conjunction with magnetic fields exotic phases of matter can be generated that are highly quantum entangled. The wave functions in these states can be probed in space and time and in quantum critical states in particular elaborate symmetries and strange properties like fractional quantum numbers are revealed. In this talk I will show some of the remarkable physics that can be explored and how neutron scattering can be used to investigate what is going on.
