Electronic screening renormalizes the linear bands of graphene and in thevicinity of the Dirac point, creates a diamond shaped structure in thequasiparticle spectral density. This is a result of electron-plasmon scatteringprocesses which produce a finite momentum feature referred to as the `plasmaronring'. In this work we explore the effects of uniaxial strain on these spectralfeatures with the aim of understanding how strain modifies correlations. Wederive and calculate the spectral density to the G$_0$W-RPA level which allowsus to identify the dispersive behaviour of the diamond geometry, and thuselectron-plasmon scattering, for variation in electron-electron couplingstrength and magnitude of applied strain. We find that the application ofstrain changes the geometry (in momentum) of the electron-plasmon scatteringand that renormalizations beyond simple geometrical scalings further enhancethis effect. These results suggest that the properties of the plasmaron ringcan be tuned through the application of uniaxial strain, effectively producinga larger fine structure constant without the need to change the samplesubstrate.
