There's not much to verify there. They claim they got a way to use electromagnetic time crystals as an electromagnetic sensor. It's not an extraordinary claim, but they don't exactly say how either, so we can't check.

And if they improve their sensor into something that seems viable, it would be good at detecting the minuscule fields that some candidate dark matter particles should create very rarely when they interact with something. Maybe becoming a better detector for them than the current state of the art (this, I think: https://en.wikipedia.org/wiki/Axion_Dark_Matter_Experiment).
