# Effect of dynamical screening on single-particle spectral features of uniaxially strained graphene : Tuning the plasmaron ring

@article{LeBlanc2013EffectOD, title={Effect of dynamical screening on single-particle spectral features of uniaxially strained graphene : Tuning the plasmaron ring}, author={J. P. F. LeBlanc and Jules P. Carbotte}, journal={Physical Review B}, year={2013}, volume={87} }

Electronic screening renormalizes the linear bands of graphene and in the vicinity of the Dirac point, creates a diamond shaped structure in the quasiparticle spectral density. This is a result of electron-plasmon scattering processes which produce a finite momentum feature referred to as the `plasmaron ring'. In this work we explore the effects of uniaxial strain on these spectral features with the aim of understanding how strain modifies correlations. We derive and calculate the spectral… Expand
