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…
New techniques and results for worldline simulations of lattice field theories
Mario Giuliani, Oliver Orasch, Christof Gattringer
We use the complex field at finite density as a model system for developing further techniques based on worldline formulations of lattice field theories. More specifically we…
Density of States FFA analysis of SU(3) lattice gauge theory at a finite density of color sources
Mario Giuliani, Christof Gattringer
We present a Density of States calculation with the Functional Fit Approach (DoS FFA) in SU(3) lattice gauge theory with a finite density of static color sources. The DoS FFA uses…
Remarks on the construction of worm algorithms for lattice field theories in worldline representation
Mario Giuliani, Christof Gattringer
We introduce a generalized worldline model where the partition function is a sum over configurations of a conserved flux on a d-dimensional lattice. The weights for the configurati…
Functional Fit Approach (FFA) for Density of States method: SU(3) spin system and SU(3) lattice gauge theory with static color sources
Mario Giuliani
We apply a recently developed variant of the Density of States (DoS) method, the so-called Functional Fit Approach (FFA) to two different models: the SU(3) spin model and SU(3) lat…
