Analysis
This paper investigates the pairing symmetry of the unconventional superconductor MoTe2, a Weyl semimetal, using a novel technique based on microwave resonators to measure kinetic inductance. This approach offers higher precision than traditional methods for determining the London penetration depth, allowing for the observation of power-law temperature dependence and the anomalous nonlinear Meissner effect, both indicative of nodal superconductivity. The study addresses conflicting results from previous measurements and provides strong evidence for the presence of nodal points in the superconducting gap.
Key Takeaways
- •Utilizes a novel technique based on microwave resonators to measure kinetic inductance in MoTe2.
- •Provides evidence for nodal superconductivity in MoTe2.
- •Addresses conflicting results from previous measurements of the London penetration depth.
Reference
“The high precision of this technique allows us to observe power-law temperature dependence of $λ$, and to measure the anomalous nonlinear Meissner effect -- the current dependence of $λ$ arising from nodal quasiparticles. Together, these measurements provide smoking gun signatures of nodal superconductivity.”
