Interplay of nematicity and orbital order with non-Fermi liquid physics

ORAL  · Invited

Abstract

Multiorbital models for correlated quantum materials naturally describe a wealth of broken symmetry phases including nematicity arising from orbital order. We explore the interplay of this nematicity with non-Fermi liquid behavior using generalizations of the Sachdev-Ye-Kitaev model to describe transport and elastotransport. Our results are of broad interest for the cuprates which exhibit oxygen orbital ordering, and the iron chalcogenides with dxz/dyz orbitals.
