  • Amplitudes de fotones en el formalismo línea de mundo 
    López Arcos, Cristhiam Manuel (Universidad Michoacana de San Nicolás de Hidalgo, 2010-01)
    Feynman grams (eg not to be regularized; a single integral represents all permutations of diagrams). After the brief introduction on the development of amplitudes of the photons begins the work of the thesis, where some ...
  • Corrección gravitacional dominante al Lagrangiano de Euler – Heisenberg Escalar 
    Dávila Dávila, José Manuel (Universidad Michoacana de San Nicolás de Hidalgo, 2008-03)
    The history of relativistic quantum electrodynamics (QED) begins in 1928 with the famous article by Dirac [1], where he proposes his wave equation relativistic view of the electron. As is well known, his work the correct ...
  • Cotas fenomenológicas para el parámetro libre de la teoría Born-Infeld 
    Trejo Espinosa, María Anabel (Universidad Michoacana de San Nicolás de Hidalgo, 2011-08)
    In Chapter 2 of this thesis we will study the Born-Infeld theory, exemplifying the changes that produces in some systems. In Chapter 3 we will study the photon-photon dispersion in the QED. In Chapter 4 we will study the ...
  • Dos estudios sobre no linealidad en teorías de campo 
    Arjang, Mona (Universidad Michoacana de San Nicolás de Hidalgo, 2014-07)
    In the first part, we present a framework for discrete spacetime classical field theory in which solutions to the field equations over elementary spacetime cells may be amalgamated if they satisfy simple gluing conditions ...
  • Estados ligados en el formalismo línea de mundo 
    Trejo Espinosa, María Anabel (Universidad Michoacana de San Nicolás de Hidalgo, 2017-08)
    Using worldline numerics we are able of generate paths with Gaussian distribution to numerically approximate the propagator of arbitrary potentials. In particular, we focus on the study of nonrelativistic quantum bound ...
  • Off-shell four photon amplitudes in the worldline formalism 
    Lopez Lopez, Misha Arturo (Universidad Michoacana de San Nicolás de Hidalgo, 2018-08)
    In this thesis, we obtain the exact result for the one-loop o-shell four-photon amplitude in D dimension and with one, two and four photons in the low energy limit in both, scalar and spinor quantum electrodynamics. For ...
  • La teoría de Einstein-Maxwell al nivel de un lazo usando el formalismo línea de mundo 
    Dávila Dávila, José Manuel (Universidad Michoacana de San Nicolás de Hidalgo, 2011-02)
    In this thesis we developed the world line formalism as a very efficient tool for calculating the effective action in the Einstein-Maxwell theory due to a scalar or spinor loop. The calculation is performed in the limit ...
