In the present work we will show a brief introduction to Wordline formalism, used for the quantization of fields and the calculation of quantities of the Quantum Field Theory such as dispersions, affective actions, anomalies, ...

In this work the generalization of the Landau-Khalatnikov-Fradkin transformations in the spinor quantum electrodynamics through the world-line formalism is developed. For this, the path integral formalism in the ordinary ...

We introduce a simple modification to Monte Carlo simulations of the Feynman path integral to improve sampling of localized interactions. We develop new algorithms that generate an ensemble of trajectories in simple ...
