Giant transverse magnetic fluctuations at the edge of re-entrant superconductivity in UTe$_{2}$ Open
UTe$_{2}$ exhibits the remarkable phenomenon of re-entrant superconductivity, whereby the zero-resistance state reappears above 40 tesla after being suppressed with a field of around 10 tesla. One potential pairing mechanism, invoked in th…
