U(1)-gauged 2-flavor spin system in 3-D
Christof Gattringer, Tin Sulejmanpasic
We study a U(1)-gauged 2-component spin system in 3 dimensions. For the gauge fields we use the Villain formulation with a constraint that removes lattice monopoles and in this for…
Density of states techniques for fermion worldlines
Christof Gattringer
Worldline representations were established as a powerful tool for studying bosonic lattice field theories at finite density. For fermions, however, the worldlines still may carry s…
Massless Schwinger model with a 4-fermi interaction at topological angle
Dominic Hirtler, Christof Gattringer
We study the massless Schwinger model with an additional 4-fermi interaction and a topological term. For topological angle charge conjugation symmetry is implemented in a no…
Phase structure of self-dual lattice gauge theories in 4d
Mariia Anosova, Christof Gattringer, Nabil Iqbal +1
We discuss U(1) lattice gauge theory models based on a modified Villain formulation of the gauge action, which allows coupling to bosonic electric and magnetic matter. The formulat…
Self-dual U(1) lattice field theory with a -term
Mariia Anosova, Christof Gattringer, Tin Sulejmanpasic
We study U(1) gauge theories with a modified Villain action. Such theories can naturally be coupled to electric and magnetic matter, and display exact electric-magnetic duality. In…
Density of states approach for lattice field theory with topological terms
Christof Gattringer, Oliver Orasch
We discuss a new density of states (DoS) approach to solve the complex action problem that is caused by topological terms. The key ingredient is to use open boundary conditions for…
