Dual representation for massless fermions with chemical potential and U(1) gauge fields
Christof Gattringer, Thomas Kloiber, Vasily Sazonov
Complex action problems coming from either a chemical potential or a topological term have been solved for several models in recent years by mapping them to so-called dual degrees…
Dual representation for 1+1 dimensional fermions interacting with 3+1 dimensional U(1) gauge fields
Christof Gattringer, Vasily Sazonov
We study a system of nanowires, i.e., the theory of 1+1 dimensional massless fermions interacting with 3+1 dimensional U(1) gauge fields. When allowing for non-zero chemical potent…
Convergent Perturbation Theory for the lattice -model
Vladimir V. Belokurov, Aleksandr S. Ivanov, Vasily K. Sazonov +1
The standard lattice perturbation theory leads to the asymptotic series because of the incorrect interchange of the summation and integration. However, changing the initial approxi…
Convergent series for QCD
V. K. Sazonov
We present the construction of the convergent series for Quantum Chromodynamics in the Euclidean space. Applying the bosonization, we rewrite QCD as the five-dimensional bosonic ve…
Solving the sign problems of the massless lattice Schwinger model with a dual formulation
Christof Gattringer, Thomas Kloiber, Vasily Sazonov
We derive an exact representation of the massless Schwinger model on the lattice in terms of dual variables which are configurations of loops, dimers and plaquette occupation numbe…
