We show that the current thermodynamic measurements in the superconducting phase of URu2Si2 are compatible with two distinct singlet chiral paired states kz(kx± iky) and (kx± iky). Depending on the locations of the Fermi surface in the hidden ordered phase, both of these chiral d-wave pairings can support point and line nodes. Despite possessing similar low temperature thermodynamic properties, these two pairings are topologically distinguished by their respective orbital angular momentum… CONTINUE READING
