Fermionic fields in the pseudoparticle approach

Understand

The pseudoparticle approach is a numerical method to compute path integrals without discretizing spacetime.

• The basic idea is to consider only those field configurations, which can be represented as a linear superposition of a small number of localized building blocks (pseudoparticles), and to replace the functional integration by an integration over the pseudoparticle degrees of freedom.
• In previous papers we have successfully applied the pseudoparticle approach to SU(2) Yang-Mills theory.
• In this work we discuss the inclusion of fermionic fields in the pseudoparticle approach.
