Electron irradiation effects on superconductivity in PdTe2: An application of a generalized Anderson theorem

This paper presents a systematic experimental study of the impact of disorder induced by electron irradiation on the superconducting phase of the Dirac semimetal PdTe2. Using a recently derived generalized version of the Anderson theorem, the authors obtain quantitative constraints on the pairing state. This leaves an unconventional superconducting phase as the most natural candidate order.
