SUMMARY:Probing Exotic Superconductors with Cryomagnetic Scanning Tunneling
  Spectroscopy
DESCRIPTION:John Wei\, Department of  Physics\, University of TorontoCryog
 enic scanning tunneling spectroscopy (STS) has long been useful for the st
 udy of superconductors\, with its ability to measure the quasiparticle exc
 itation spectrum down to atomic length scales.  Its application in a mag
 netic field has also enabled the imaging of superconducting vortex lattice
 s and probing of bound states inside vortex cores.  Recent advances in c
 ryomagnetic STS are helping to shed powerful light on a number of exotic s
 uperconductors\, i.e. characterized by unconventional pairing symmetries\,
  complex band structures and/or competing order parameters.  In this tal
 k I will briefly survey these advances\, and report on a new class of cryo
 magnetic STS experiments -- performed at 300 mK and up to 9 Tesla -- desig
 ned to probe superconductivity under finite superfluid momentum.Site web d
