Multiple Superconducting Phases in UTe_{2}: A Complex Analogy to Superfluid Phases of ^{3}He
202133
In quantum liquids, large differences are observed owing to differences in quantum statistics. The physical properties of liquid ^{3}He (Fermion) and ^{4}He (Boson) are considerably different at low temperatures. After the discovery of superconductivity in electron (i.e., Fermion) systems, a similar pairing ordered state was expected for ^{3}He. Remarkably, the observed ordered state of ^{3}He was more surprising than expected, multiple superfluid phases in the T–P phase diagram. The origin of the multiple phases was attributed to ferromagnetic interactions in the pwave symmetry state.
