Title of the talk:
"Almost failed magnets: Ordered states on the brink of liquidity" - Professor Arun Paramekanti from the University of Toronto, Canada.
Abstract:
This is a story about solids which almost fail to magnetically order, where the crystal geometry or competing interactions lead to weak order with signs of spin liquidity found in their dynamical response. We will discuss examples from honeycomb and triangular magnets where numerical results and analytical methods can shed light on the phase diagrams and dynamical responses which can be observed in THz spectroscopy and inelastic neutron scattering experiments.
