Single thermodynamic transition at 2 K in superconducting UTe2 single crystals
Single thermodynamic transition at 2 K in superconducting UTe2 single crystals
UTe2 is a newly-discovered unconventional superconductor wherein multicomponent topological superconductivity is anticipated based on the presence of two superconducting transitions and time-reversal symmetry breaking in the superconducting state. The observation of two superconducting transitions, however, remains controversial. Here we demonstrate that UTe2 single crystals displaying an optimal superconducting transition temperature …
