Evidence of a Phonon Hall Effect in the Kitaev Spin Liquid Candidate $\alpha$-RuCl${}_3$

É. Lefrançois, G. Grissonnanche, J. Baglo +9

The material $\alpha$-RuCl${}_3$ has been the subject of intense scrutiny as a potential Kitaev quantum spin liquid, predicted to display Majorana fermions as low energy excitations. In p…
