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…
Low temperature condensation and scattering data
Oliver Orasch, Christof Gattringer, Mario Giuliani
We study lattice field theory at finite chemical potential in two and four dimensions, using a worldline representation that overcomes the complex action problem. We comp…
Finite density condensation and scattering data - a study in lattice field theory
Christof Gattringer, Mario Giuliani, Oliver Orasch
We study the quantum field theory of a charged field in lattice regularization at finite density and low temperature in 2 and 4 dimensions with the goal of analyzing the conn…
