Screening and anti-screening in QED and in Weyl semimetals [PDF]
D. N. VoskresenskyDistributions of charge near charged impurities in Weyl semimetals are considered with the help of relativistic Thomas-Fermi method in full analogy with the solutions previously found in QED. Screening and anti-screening, zero charge and asymptotic freedom solutions appearing in different physical situations are discussed.View original: http://arxiv.org/abs/1208.5163
