Investigation of the Nicole model
C. Adam, J. Sanchez-Guillen, R. A. Vazquez +1
We study soliton solutions of the Nicole model - a non-linear four-dimensional field theory consisting of the CP^1 Lagrangian density to the non-integer power 3/2 - using an ansatz…
New tests and applications of the worldline path integral in the first order formalism
C. D. Fosco, J. Sanchez-Guillen, R. A. Vazquez
We present different non-perturbative calculations within the context of Migdal's representation for the propagator and effective action of quantum particles. We first calculate th…
Quantum effective actions from nonperturbative worldline dynamics
H. Gies, J. Sánchez--Guillén, R. A. Vázquez
We demonstrate the feasibility of a nonperturbative analysis of quantum field theory in the worldline formalism with the help of an efficient numerical algorithm. In particular, we…
