Strontium ruthenate Sr 2 RuO 4 is an unconventional superconductor whose pairing
symmetry has not been fully clarified, despite more than two decades of intensive research …

The characteristic excitation of a metal is its plasmon, which is a quantized collective
oscillation of its electron density. In 1956, David Pines predicted that a distinct type of …

The role of X-ray based electron spectroscopies in determining chemical, electronic, and
magnetic properties of solids has been well-known for several decades. A powerful …

We explore the interplay of electron-electron correlations and spin-orbit coupling in the
model Fermi liquid Sr 2 RuO 4 using laser-based angle-resolved photoemission …

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 …

We study the superconductivity pairing symmetry in Sr 2 RuO 4 in the limit of small
interaction by extending a renormalization group calculation developed by Raghu et …

The unconventional superconductor Sr 2 RuO 4 has been the subject of enormous interest
over more than two decades, but until now the form of its order parameter has not been …

Standard superconductors display a ubiquitous discontinuous jump in the electronic specific
heat at the critical superconducting transition temperature. In a growing class of …

The possible superconducting states of strontium ruthenate (Sr 2 RuO 4) are organized into
irreducible representations of the point group D 4 h, with a special emphasis on nodes …

We use the functional renormalization group method to study a three-orbital model for
superconducting Sr 2 RuO 4. Although the pairing symmetry is found to be a chiral p wave …
