Probing unification scenarios with atomic clocks
M. C. Ferreira, M. D. Julião, C. J. A. P. Martins +1
We discuss the usage of measurements of the stability of nature's fundamental constants coming from comparisons between atomic clocks as a means to constrain coupled variations of…
Accurate Calibration of the Velocity-dependent One-scale Model for Domain Walls
A. M. M. Leite, C. J. A. P. Martins, E. P. S. Shellard
We study the asymptotic scaling properties of standard domain wall networks in several cosmological epochs. We carry out the largest field theory simulations achieved to date, with…
Cosmic string evolution with a conserved charge
M. F. Oliveira, A. Avgoustidis, C. J. A. P. Martins
Cosmic strings with degrees of freedom beyond the standard Abrikosov-Nielsen-Olesen or Nambu-Goto strings are ubiquitous in field theory as well as in models with extra dimensions,…
