Cryogenic scanning tunneling spectroscopy (STS) has long been useful for the study of superconductors, with its ability to measure the quasiparticle excitation spectrum down to atomic length scales. Its application in a magnetic field has also enabled the imaging of superconducting vortex lattices and probing of bound states inside vortex cores. Recent advances in cryomagnetic STS are helping to shed powerful light on a number of exotic superconductors, i.e. characterized by unconventional pairing symmetries, complex band structures and/or competing order parameters. In this talk I will briefly survey these advances, and report on a new class of cryomagnetic STS experiments -- performed at 300 mK and up to 9 Tesla -- designed to probe superconductivity under finite superfluid momentum.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
