Absence of Debye Screening in the Quantum Coulomb System (2007)
We present an approximation to the quantum Coulomb plasma at equilibrium which captures the power-law violations of Debye screening which have been reported in recent papers. The objectives are: (1)...

Perturbative Renormalization with Flow Equations in Minkowski Space (1996)
Keller, Georg, Kopper, Christoph, Schophaus, Clemens
We show within the Wilson renormalization group framework how the flow equation method can be used to prove the perturbative renormalizability of a relativistic massive selfinteracting scalar field....
