Spin waves in a two dimensional p-wave superconductor: Sr${}_2$RuO${}_4$

Abstract

We study spin excitations in a two dimensional p-wave superconductor with $\vec{\Delta }=\hat{d}({\hat{k}}_1\pm i{\hat{k}}_2)$ symmetry in the context of the newly discovered superconducting Sr${}_2$RuO${}_4$. The polarization and spectrum of spin wave excitations are identified and their experimental consequences are discussed.
