Landau-khalatnikov equation
TīmeklisThe model self-consistently solves 2D Poisson's equation, non-equilibrium Green's function (NEGF) based charge and transport equations, and multi-domain Landau Khalatnikov (LK) equations with the domain interaction term. TīmeklisQED are the Landau-Khalatnikov-Fradkin transformations (LKFTs), which describe how the individual Green func-tions respond to an arbitrary gauge transformation [18,19]. TheLKFTs areawell-defined set of transformations which leave the DSEs and related WTIs of the fermion-boson vertex form invariant. While the STIs are the QCD
