Rice University physicists built magnetoARPES, a new instrument that revealed the first direct momentum-space evidence of time-reversal symmetry breaking in the kagome superconductor CsV3Sb5, confirming theoretically predicted loop current orders.

A Kyoto University team applied three types of shear strain to ultra-thin crystals of the unconventional superconductor Sr2RuO4 and found virtually no change in its transition temperature, ruling out several leading theoretical models and opening new questions about the material's pairing symmetry.
