Measuring dynamical correlations in quantum magnets with neutron scattering
Prof. Alan Tennant, HMI Berlin
Quantum magnets provide paradigms of strongly correlated behaviour that
have proved an inspiration for condensed matter physics generally from
fractionalization of quantum numbers and topological excitations to
novel superconductivity mechanisms. Neutron scattering provides an
unrivalled experimental tool allowing this physics to be explored in
remarkable depth. In this talk I present an overview of the principles
involved and current research in this field including examples of
quantum phase transitions and novel quantum states.
