Special Quantum Matter Seminar

Spin triplet superconductors are among the most exotic of quantum materials, breaking both particle-number conservation and spin-rotation symmetry. As a consequence, the superfluid and spin dynamics of a triplet condensate are intertwined, and their interplay can lead to new phenomena. In this talk, I will discuss two such dynamical phenomena in triplet superconductors. First, I will discuss the microwave response of induced superconductivity in a superconductor/ferromagnet hybrid system, probed using techniques from circuit quantum electrodynamics. Second, I will discuss the electrodynamic collective response of intrinsic triplet superconductors, including their ability to host surface-localized spin wave modes and how these spin waves may be relevant to the recently discovered spin triplet states in graphene heterostructures.
