Field theoretic study of electron-electron interaction effects in Dirac liquids
S. Teber
The aim of this habilitation thesis is to present recent results, obtained during the period 2012-2017, related to interaction effects in condensed matter physics systems such as p…
Multi-loop techniques for massless Feynman diagram calculations
A. V. Kotikov, S. Teber
We review several multi-loop techniques for analytical massless Feynman diagram calculations in relativistic quantum field theories: integration by parts, the method of uniqueness,…
Field theoretic renormalization study of interaction corrections to the universal ac conductivity of graphene
S. Teber, A. V. Kotikov
The two-loop interaction correction coefficient to the universal ac conductivity of disorder-free intrinsic graphene is computed with the help of a field theoretic renormalization…
Field theoretic renormalization study of reduced quantum electrodynamics and applications to the ultra-relativistic limit of Dirac liquids
S. Teber, A. V. Kotikov
The field theoretic renormalization study of reduced quantum electrodynamics (QED) is performed up to two loops. In the condensed matter context, reduced QED constitutes a very nat…
