Query: Manipulating superconductivity in ruthenates through Fermi surface
  engineering   The key challenge in superconductivity research is to go beyond the
historical mode of discovery-driven research. We put forth a new strategy,
which is to combine theoretical developments in the weak-coupling
renormalization group approach with the experimental developments in lattice
strain driven Fermi surface-engineering. For concreteness we theoretically
investigate how superconducting tendencies will be affected by strain
engineering of ruthenates' Fermi surface. We first demonstrate that our
approach qualitatively reproduces recent experiments under uniaxial strain. We
then note that order few $\%$ strain readily accessible to epitaxial thin
films, can bring the Fermi surface close to van Hove singularity. Using the
experimental observation of the change in the Fermi surface under biaxial
epitaxial strain and ab-initio calculations, we predict ${\rm T}_{\rm c}$ for
triplet pairing to be maximized by getting close to the van Hove singularities
without tuning on to the singularity.
