Abstract: “Understanding superconductors that fall outside the Bardeen-Cooper-Schrieffer paradigm remains one of the major frontiers in condensed matter physics, both because of the intellectual challenges it poses and because of the technological breakthroughs that it could yield in quantum computation and energy technologies. In this talk I will argue that progress in this field has been accelerating in recent years, an argument that will focus on developments in two major areas. The first is the discovery of superconductivity in uranium ditelluride (UTe2). This material shows a plethora of superconducting phases, some of which only appear reentrantly at magnetic fields as high as 60 tesla. I will review the evidence for triplet pairing in this material and discuss the lessons that it offers for finding more triplet superconductors. The second recent development that I will focus on is an emerging universal phenomenology among the high-Tc cuprate and iron-pnictide materials. I will review a series of experiments that extend old observations about the link between T-linear resistivity and superconductivity to new observations about charge transport behavior as a function of magnetic field, and argue that this apparent universality brings us closer to understanding the minimum requirements for unconventional superconductivity.”
