This review describes recent significant research developments made on the layered
perovskite Sr2RuO4 and discusses current issues from both experimental and theoretical …

Symmetry breaking beyond a global U (1) phase is the key signature of unconventional
superconductors. As prototypical strongly correlated materials, heavy-fermion metals …

Many seemingly contradictory experimental findings concerning the superconducting state
in Sr 2 RuO 4 can be accounted for on the basis of a conjectured accidental degeneracy …

We report on measurements of the in-plane magnetic penetration depth (λ ab) in single
crystals of Sr 2 RuO 4 down to≃ 0.015 K by means of muon-spin rotation-relaxation. The …

We revisit the concept of nonunitary superconductivity and generalize it to address complex
quantum materials. Starting with a brief review of the notion of nonunitary superconductivity …

Uniaxial-strain experiments have become a powerful tool to unveil the character of
unconventional phases of electronic matter. Here, we propose a combination of the …

Despite many experimental and theoretical efforts, the pairing symmetry of superconductivity
in Sr 2 RuO 4 remains undecided. The accidentally degenerate dx 2− y 2+ ig is consistent …

The family of multilayered superconductors derived from doped topological insulators in the
family of Bi 2 Se 3 has been found to be unusually robust against nonmagnetic disorder …

Sr2RuO4 was for a long time considered to be a superconductor with odd-parity spintriplet
pairing, which is sought after for the possibility of hosting Majorana fermions. A new …
