Search for charge neutral majorana fermions in SmB<sub>6</sub> under uniaxial strain

ORAL

Abstract

The existence of a charge neutral fermi surface as evidenced from measurements of a large three dimensional fermi surface has motivated renewed interest in the bulk of samarium hexaboride. Thermal transport measurements have been performed using both flux and floating grown zone crystals, each resulting in different conclusions regarding a fermionic contribution suggestive of these charge neutral majorana fermions. Uniaxial strain has been shown to tune the mixed valence physics in the bulk and as such may be critical in understanding the underlying behavior of SmB6. Here we report our progress on thermal transport on SmB6 under uniaxial strain
