Query: Tests of nematic-mediated superconductivity applied to
  Ba$_{1-x}$Sr$_x$Ni$_2$As$_2$   In many unconventional superconductors, nematic quantum fluctuations are
strongest where the critical temperature is highest, inviting the conjecture
that nematicity plays an important role in the pairing mechanism. Recently,
Ba$_{1-x}$Sr$_x$Ni$_2$As$_2$ has been identified as a tunable nematic system
that provides an ideal testing ground for this proposition. We therefore
propose several sharp empirical tests, supported by quantitative calculations
in a simple model of Ba$_{1-x}$Sr$_x$Ni$_2$As$_2$. The most stringent
predictions concern experiments under uniaxial strain, which has recently
emerged as a powerful tuning parameter in the study of correlated materials.
Since uniaxial strain so precisely targets nematic fluctuations, such
experiments may provide compelling evidence for nematic-mediated pairing,
analogous to the isotope effect in conventional superconductors.
