Irrelevant Interactions without Composite Operators - A Remark on the Universality of Second Order Phase Transitions
Christoph Kopper, Walter Pedra
We study the critical behaviour of symmetric theory including irrelevant terms of the form in the bare action, where is the UV cutoff (correspondi…

Singularity Cancellation in Fermion Loops through Ward Identities
C. Kopper, J. Magnen
Recently Neumayr and Metzner have shown that the connected N-point density- correlation functions of the two-dimensional and the one-dimensional Fermi gas at one-loop order generic…

Temperature Independent Renormalization of Finite Temperature Field Theory
Christoph Kopper, Volkhard F. Müller, Thomas Reisz
We analyse 4-dimensional massive $\vp^4$ theory at finite temperature T in the imaginary-time formalism. We present a rigorous proof that this quantum field theory is renormalizabl…
