Pair Density Wave Mania!
Two QMC collaborations - with the Madhavan group at the University of Illinois-Urbana Champaign and the Davis group at Cornell University, University College Cork and Oxford University - have found striking instances of charge- and pair-density wave orders in the topological spin-triplet superconductor UTe2 using scanning tunneling microscopy techniques. The Madhavan group, who previously discovered chiral superconductivity in this material, unveiled an unusual kind of charge-density-wave order that is closely associated with superconductivity and is sensitive to magnetic fields. The Davis group used a superconducting Nb tip to identify the presence of three pair density waves along the same directions as the Urbana charge density waves.
