A first look at Structured-Multiscale Algebraic Multigrid for Lattice Field Theory
Pauline Schauerte, Jaime Fabián Nieto Castellanos, Arnold Krechel +2
State-of-the-art solvers for the Dirac equation in Lattice QCD are based on adaptive multigrid methods. These require fine-tuning of many algorithmic parameters to achieve optimal…
A pion decay constant in the multi-flavor Schwinger model
Jaime Fabián Nieto Castellanos, Ivan Hip, Wolfgang Bietenholz
The pion decay constant plays an important role in QCD and in Chiral Perturbation Theory. It is hardly known, however, that a corresponding constant exists in the Schwinger m…
Non-equilibrium dynamics of topological defects in the 3d O(2) model
Edgar López-Contreras, Jaime Fabián Nieto Castellanos, Elías Natanael Polanco-Euán +1
We present a study of the 3d O(2) non-linear -model on the lattice, which exhibits topological defects in the form of vortices. They tend to organize into vortex lines that bear…
An analogue to the pion decay constant in the multi-flavor Schwinger model
Jaime Fabián Nieto Castellanos, Ivan Hip, Wolfgang Bietenholz
We study the Schwinger model with degenerate fermion flavors, by means of lattice simulations. We use dynamical Wilson fermions for , and re-weigh…
New insight in the 2-flavor Schwinger model based on lattice simulations
Jaime Fabián Nieto Castellanos, Wolfgang Bietenholz, Ivan Hip
We consider the Schwinger model with two degenerate, light fermion flavors by means of lattice simulations. At finite temperature, we probe the viability of a bosonization method b…
Finite temperature and delta-regime in the 2-flavor Schwinger model
Ivan Hip, Jaime Fabián Nieto Castellanos, Wolfgang Bietenholz
The Schwinger model is often used as a testbed for conceptual and numerical approaches in lattice field theory. Still, some of its rich physical properties in anisotropic volumes h…
