Approximate solution of two dimensional disc-like systems by one dimensional reduction: an approach through the Green function formalism using the Finite Elements Method
Alejandro Ferrero, Juan Pablo Mallarino
We present a comprehensive study for common second order PDE's in two dimensional disk-like systems and show how their solution can be approximated by finding the Green function of…
Solution to the -functions in Lorentz-violating theories as a decomposition into irreducible representations
Alejandro Ferrero
We analyze the -functions of Yukawa and electromagnetic theories with Lorentz violation (LV) and propose an alternative method to find the scale dependence of the different fiel…
Screening of an electrically charged particle in a two-dimensional two-component plasma at
Alejandro Ferrero, Gabriel Téllez
We consider the thermodynamic effects of an electrically charged impurity immersed in a two-dimensional two-component plasma, composed by particles with charges , at tempera…
Quantum Effects of a Spacetime Varying alpha on the Propagation of Electrically Charged Fermions
Alejandro Ferrero, Brett Altschul
A spacetime-varying fine structure constant alpha(x^mu) could generate quantum corrections in some of the coefficients of the Lorentz-violating standard model extension (SME) assoc…
Renormalization of Scalar and Yukawa Field Theories with Lorentz Violation
Alejandro Ferrero, Brett Altschul
We consider a theory of scalar and spinor fields, interacting through Yukawa and phi^4 interactions, with Lorentz-violating operators included in the Lagrangian. We compute the lea…
Limits on the Time Variation of the Fermi Constant G_F Based on Type Ia Supernova Observations
Alejandro Ferrero, Brett Altschul
The light curve of a type Ia supernova decays at a rate set by the beta-decay lifetimes of the Ni-56 and Co-56 produced in the explosion. This makes such a light curve sensitive to…
