In this short review, we aim to provide a topical update on the status of efforts to understand
the superconductivity of Sr2RuO4. We concentrate on efforts to identify a superconducting …

Abstract Majorana fermions are spin-1/2 neutral particles that are their own antiparticles and
were initially predicted by Ettore Majorana in particle physics but their observation still …

Phases of matter are usually identified through spontaneous symmetry breaking, especially
regarding unconventional superconductivity and the interactions from which it originates. In …

Sr2RuO4 has stood as the leading candidate for a spin-triplet superconductor for 26 years.
However, recent NMR experiments have cast doubt on this candidacy, and it is difficult to …

Strontium ruthenate (Sr 2 RuO 4) has long been thought to host a spin-triplet chiral p-wave
superconducting state. However, the singletlike response observed in recent spin …

A variety of precise experiments have been carried out to establish the character of the
superconducting state in Sr2RuO4. Many of these appear to imply contradictory conclusions …

Unambiguous identification of the superconducting order parameter symmetry in Sr 2 RuO 4
has remained elusive for more than a quarter century. While a chiral p-wave ground state …

The quasi-two-dimensional metal Sr2RuO4 is one of the best characterized unconventional
superconductors, yet the nature of its superconducting order parameter is still under debate …

Recent nuclear magnetic resonance studies [A. Pustogow et al., Nature 574, 72 (2019)]
have challenged the prevalent chiral triplet pairing scenario proposed for Sr 2 RuO 4. To …

Topological superconductors (TSCs) have garnered significant research and industry
attention in the past two decades. By hosting Majorana bound states which can be used as …
