Superfluid Stiffness of T<sup>d</sup>-MoTe<sub>2</sub> at Microwave Frequencies

ORAL

Abstract

Superfluid stiffness is an intrinsic property that we leverage to reveal information about the pairing symmetry in superconductors. Robust cQED theory and technique allow us to measure the superfluid stiffness of MoTe2 to parts per million precision as a function of temperature and power. Measurements show evidence of nodal superconductivity and a non-linear Meissner effect in Td-MoTe2. Furthermore, we develop a novel microwave pump-probe technique to study the recombination time, aiming to understand the Cooper-pairing mechanism of Weyl superconductivity in Td-MoTe2.
