Linnaeus colloquium: Signatures of broken time-reversal and mirror symmetry in unconventional superconductors

​Talk by James Sauls, professor of physics at Northwestern University, USA


​Abstract: Signatures of broken time-reversal and mirror symmetry in unconventional superconductors
​I will present a mix of theory with experimental reports on the observations of broken time-reversal and mirror symmetries(BTRP) in unconventional superconductors, focusing on Sr2RuO4, UPt3 the high-pressure phase of superfluid 3He. I will start with brief summaries of theoretical predictions for the ground states in these unconventional superconductors, the experimental evidence supporting superconductivity with BTRP and some un-resolved questions concerning the symmetry of the superconducting ground states in Sr2RuO4 and UPt3, as well as precisely why we know that 3He-A is a chiral p-wave superfluid supporting Weyl-Majorana Fermions. I will conclude with theoretical results for anomalous Hall-type transport studies that could provide fresh insight into multi-component, unconventional superconductors.


Coffee and cake will be served 15 minutes before the seminar's start
