QED vertex and anomalous magnetic moment in the presence of a magnetic field
Alejandro Ayala, Enrique Muñoz, Marcelo Loewe +2
We compute the fermion-photon vertex in QED in the presence of a constant and uniform magnetic background up to one-loop order. We show that even at tree-level, the vertex is modif…
Electric field fluctuations and renormalization group flows in a self-interacting scalar field theory
Melanie Martínez, Enrique Muñoz, Marcelo Loewe
We consider a self interacting charged scalar field represented by the complex λϕ4 model, embedded in a background electric field exhibiting classical stochastic fluctuations. We s…
Thermal corrections to Regge trajectories
R. Cadiz, M. Loewe, R. Zamora
In this work, we investigate the behavior of Regge trajectories in the context of quantum field theory at finite temperature. For this purpose, we employ the model. We first…
Strongly interacting matter in extreme magnetic fields
Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58
Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
