Searching for Fractionalized particles in a potential Kiteav Spin Liquid

ORAL

Abstract

Relativistic Mott insulators on the honeycomb lattice are predicted to realize a novel topologically protected state known as the Kitaev Quantum Spin Liquid(QSL). Recently attention has focused on α-RuCl3 that appears to be close to this limit with preliminary evidence from Neutrons and Raman for Majorana fermions. Here I will discuss our recent high resolution Raman spectroscopy of both Stokes and anti-Stokes spectra. We find new evidence for the non-trivial nature of these excitations.
