Dynamical Linked Cluster Expansions for Spin Glasses
H. Meyer-Ortmanns, T. Reisz
Dynamical linked cluster expansions are linked cluster expansions with hopping parameter terms endowed with their own dynamics. This amounts to a generalization from 2-point to poi…
Chiral symmetry restoration and axial vector renormalization for Wilson fermions
T. Reisz, H. J. Rothe
Lattice gauge theories with Wilson fermions break chiral symmetry. In the U(1) axial vector current this manifests itself in the anomaly. On the other hand it is generally expected…
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…
The axial anomaly in lattice QED. A universal point of view
T. Reisz, H. J. Rothe
We give a perturbative proof that U(1) lattice gauge theories generate the axial anomaly in the continuum limit under very general conditions on the lattice Dirac operator. These c…
Analytical studies for the critical line and critical endpoint of the electroweak phase transition
H. Meyer-Ortmanns, T. Reisz
We outline two approaches for studying the electroweak phase transition in the framework of the four-dimensional SU(2) Higgs model on a lattice. The first one is based on a combina…
Dynamical linke cluster expansions: Algorithmic aspects and applications
H. Meyer-Ortmanns, T. Reisz
Dynamical linked cluster expansions are linked cluster expansions with hopping parameter terms endowed with their own dynamics. They amount to a generalization of series expansions…
