The analytic structure of the Landau gauge quark propagator from Padé analysis
Alexandre F. Falcão, Orlando Oliveira
The analytic structure of the 2 flavour full QCD lattice Landau gauge quark propagator is investigated with Padé approximants applied to its vector and scalar form factors. No pole…
Looking at the analytic structure of Landau gauge propagators
Orlando Oliveira, Alexandre F. Falcão, Paulo J. Silva
We report on a study of the analytical structure of the Landau gauge gluon, ghost and quark propagators taken from lattice simulations using large physical volumes, to better acces…
Padé Approximants and the analytic structure of the gluon and ghost propagators
Alexandre F. Falcão
In a Quantum Field Theory, the analytic structure of the 2-points correlation functions, ie the propagators, encloses information about the properties of the corresponding quanta,…
Light clusters in warm stellar matter: calibrating the cluster couplings
Tiago Custódio, Alexandre Falcão, Helena Pais +3
The abundances of light clusters within a formalism that considers in-medium effects are calculated using several relativistic mean-field models, with both density-dependent and de…
The analytic structure of the lattice Landau gauge gluon and ghost propagators
Alexandre F. Falcão, Orlando Oliveira, Paulo J. Silva
Starting from the lattice Landau gauge gluon and ghost propagator data we use a sequence of Padé approximants, identify the poles and zeros for each approximant and map them into t…
