Topological terms in abelian lattice field theories
M. Anosova, C. Gattringer, D. Göschl +2
In this contribution we revisit the lattice discretization of the topological charge for abelian lattice field theories. The construction departs from an initially non-compact disc…
Exploring the worldline formulation of the Potts model
Christof Gattringer, Daniel Göschl, Pascal Törek
We revisit the issue of worldline formulations for the q-state Potts model and discuss a worldline representation in arbitrary dimensions which also allows for magnetic terms. For…
The critical endpoint in the 2d U(1) gauge-Higgs model at topological angle
Daniel Göschl, Christof Gattringer, Tin Sulejmanpasic
We study 2d U(1) gauge Higgs systems with a -term. For properly discretizing the topological charge as an integer we introduce a mixed group- and algebra-valued discretization (…
Dual simulation of the massless lattice Schwinger model with topological term and non-zero chemical potential
Daniel Göschl
We discuss simulation strategies for the massless lattice Schwinger model with a topological term and finite chemical potential. The simulation is done in a dual representation whe…
