Effects of uni-axial strain on electronic nematic state in Sr$_{3}$Ru$_{2}$O$_{7}$

Sr$_{3}$Ru$_{2}$O$_{7}$ exhibits a novel electronic phase in the vicinity of a magnetic field-tuned quantum critical point. This phase shows strong anisotropy under weak symmetry-breaking fields, so it is thought to be intrinsically nematic. We study this phase under anisotropic strain, using a piezoelectric-based device that can both compress and tension samples. We find that the phase responds strongly to anisotropic strain, and discuss this result in the context of various theoretical models for the phase.
