Bag representation for composite degrees of freedom in lattice gauge theories with fermions
Carlotta Marchis, Christof Gattringer, Oliver Orasch
We explore new representations for lattice gauge theories with fermions, where the space-time lattice is divided into dynamically fluctuating regions, inside which different types…
Abelian color cycle and abelian color flux dualization methods for non-abelian lattice field theories
Carlotta Marchis
In this thesis we present the application of the \textit{abelian color cycle} (ACC) and the \textit{abelian color flux} (ACF) methods to several models: the SU(2) principal chiral…
Dual representation of lattice QCD with worldlines and worldsheets of abelian color fluxes
Carlotta Marchis, Christof Gattringer
We present a new dual representation for lattice QCD in terms of wordlines and worldsheets. The exact reformulation is carried out using the recently developed abelian color flux m…
Worldlines and worldsheets for non-abelian lattice field theories: Abelian color fluxes and Abelian color cycles
Christof Gattringer, Daniel Göschl, Carlotta Marchis
We discuss recent developments for exact reformulations of lattice field theories in terms of worldlines and worldsheets. In particular we focus on a strategy which is applicable a…
Kramers-Wannier duality and worldline representation for the SU(2) principal chiral model
Christof Gattringer, Daniel Göschl, Carlotta Marchis
In this letter we explore different representations of the SU(2) principal chiral model on the lattice. We couple chemical potentials to two of the conserved charges to induce fini…
Dualization of non-abelian lattice gauge theory with Abelian Color Cycles (ACC)
Carlotta Marchis, Christof Gattringer
We discuss a new approach to strong coupling expansion and dual representations for non-abelian lattice gauge theories. The Wilson gauge action is decomposed into a sum over "abeli…
