Determine whether nematic fluctuations contribute measurably to pairing given that coupling to lattice strain cuts off the divergence of the nematic correlation length. An answer is a quantitative estimate of the nematic contribution to the pairing interaction with an experimental test, such as $T_{c}$ versus nematic susceptibility under tuned strain.","problem_ref":"3ead336b9bdac11bd4f727aef256eb7a0334c3b6a1c52677bd4f3b0a080d1d01","references":"","settled_by":"Strain-tuned measurements of $T_{c}$ and nematic susceptibility in a single
