Exploring quantum spin liquid excitations in a Kitaev material through electronic transport measurements at low temperatures

POSTER

Abstract

Alpha-RuCl3 is a top candidate for the experimental realization of The Kitaev Model, an exactly solvable model for moments in a honeycomb lattice with direction dependent interactions. In materials such as alpha-RuCl3, interactions beyond the Kitaev model lead to an anti-ferromagnetic zizag state below 7K. Our previous electronic transport measurements have identified Efros-Shklovskii Variable-Range Hopping in a temperature range between 7K and 40K, deviating from this transport mechanism in a regime of a long range magnetic order, below 7K. Above 40K, the dominant transport mechanism is thermal activation [1]. Here, we present our current efforts to understand our results within the theory of quantum spin liquid fluctuations.
