▎ 摘  要

After deriving a general correspondence between linear response correlation functions in graphene with and without applied uniaxial strain, we study the dependence on the strain modulus and direction of selected electronic properties, such as the plasmon dispersion relation and the optical conductivity, as well as the magnetic and electric susceptibilities. Specifically, we find that the dispersion of the recently predicted transverse plasmon mode exhibits an anisotropic deviation from linearity, thus facilitating its experimental detection in strained graphene samples.
