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…
Temperature fluctuations in a relativistic gas: Pressure corrections and possible consequences in the deconfinement transition
Jorge David Castaño-Yepes, Marcelo Loewe, Enrique Muñoz +1
In this work, we study the effects of random temperature fluctuations on the equation of state of a non-interacting, relativistic fermion gas by means of the replica method. This p…
Magnetic Corrections to - Scattering Lengths in the Linear Sigma Model
M. Loewe, L. Monje, R. Zamora
In this article we consider the magnetic corrections to - scattering lengths in the frame of the linear sigma model. For this we consider all the one loop corrections in the…
Atomic Collapse in Graphene: Lost of Unitarity
David Valenzuela, Saúl Hernández-Ortiz, Marcelo Loewe +1
We explore the problem of atomic collapse in graphene by monopole impurities, both electric and magnetic, within the context of supersymmetric quantum mechanics. For electric impur…
Inverse magnetic catalysis for the chiral transition induced by thermo-magnetic effects on the coupling constant
Alejandro Ayala, M. Loewe, Ana Julia Mizher +1
We compute the one-loop thermo-magnetic corrections to the self-coupling in a model where charged scalars interact also with a constant magnetic field. The calculation is motivated…
Vacuum instability by a chromoelectric field in 2 + 1-dimensions
M. Loewe, F. Marquez, R. Zamora
The problem of vacuum instability and creation of pairs by external fields SU(2) is studied. The effective mass operator has complex eigenvalues implying decay and pair creation. W…
Finite density and temperature in hybrid bag models
M. De Francia, H. Falomir, M. Loewe
We introduce the chemical potential in a system of two-flavored massless fermions in a chiral bag by imposing boundary conditions in the Euclidean time direction. We express the fe…
Confined two-dimensional fermions at finite density
M. De Francia, H. Falomir, M. Loewe +1
We introduce the chemical potential in a system of two-dimensional massless fermions, confined to a finite region, by imposing twisted boundary conditions in the Euclidean time dir…
