Theory of Strain Effects on Extremely Correlated Metals in Two-dimensions

ORAL

Abstract

We study the strain dependence of anisotropic resistivity [1] within the t-t'-J model, applicable to cuprate superconductors. This model is treated using the recently developed extremely correlated Fermi liquid theory (ECFL). We obtain the temperature, density and strain dependence of the anisotropic resistivity. We compute the strain response functions in different geometries for comparing with planned experiments [1]. We also study the strain dependence of the optical weight and the local density of states (LDOS) at low T. Our results provide quantitative predictions of these quantities for experimental tests on strongly correlated materials such as high-Tc materials.
