Effect of strain ϵxx on the critical scale Λc for different values of U and J (a) and values of U and J for each line given in the upper right. DOS in the dxy orbital depends on ϵ (b) and theoretically predicted enhancement of Λc due to uniaxial strain as a function of its value for ϵxx = 0 (c). Each dotted line in the upper left plot corresponds to one U − J combination given in the upper right. There is a clear correlation between Λc(ϵxx = 0) and the ratio of increase in Tc which can be seen in both a, c. The experimental data points in c are extracted from ref. 33. A proposed mechanism that explains this enhancement is detailed in the text.
