# Dynamical polarization, plasmon model, and the Friedel oscillation of the screened potential in doped Dirac and Weyl system

@article{Wu2018DynamicalPP, title={Dynamical polarization, plasmon model, and the Friedel oscillation of the screened potential in doped Dirac and Weyl system}, author={Chen Wu}, journal={arXiv: Mesoscale and Nanoscale Physics}, year={2018} }

We discuss the dynamical polarization, plasmon dispersion, relaxation time, and the Friedel oscillation of screened potential of the two-dimension Dirac and three-dimension Weyl system (which are gapped) in the low-energy tigh-binding model. The results, like the Fermi wavevector, Thomas-Fermi wavevector, and longitudinal conductivity are obtained in different dimensions. Some important conclusions are detailedly discussed in this paper, including the screening character under short or long…
