Domain wall evolution beyond quartic potentials: The Sine-Gordon and Christ-Lee potentials
R. Heilemann, M. C. Rosa, J. R. C. C. C. Correia +1
Domain walls are the simplest type of topological defects formed at cosmological phase transitions, and one of the most constrained. Their studies typically assume a quartic double…
Evolution of current-carrying string networks
J. R. C. C. C. Correia, C. J. A. P. Martins, F. C. N. Q. Pimenta
Cosmic string networks are expected to form in early Universe phase transitions via the Kibble mechanism and are unavoidable in several Beyond the Standard Model theories. While mo…
Multitension strings in high-resolution U(1)U(1) simulations
J. R. C. C. C. Correia, C. J. A. P. Martins
Topological defects are a fossil relic of early Universe phase transitions, with cosmic strings being the best motivated example. While in most cases one studies Nambu-Goto or Abel…
High resolution calibration of string network evolution
J. R. C. C. C. Correia, C. J. A. P. Martins
The canonical velocity-dependent one-scale (VOS) model for cosmic string evolution contains a number of free parameters which cannot be obtained ab initio. Therefore it must be cal…
High resolution calibration of the cosmic strings velocity dependent one-scale model
J. R. C. C. C. Correia, C. J. A. P. Martins
The canonical velocity-dependent one-scale (VOS) model for cosmic string evolution must be calibrated using high resolution numerical simulations, We exploit our state of the art g…
Quantifying the effect of cooled initial conditions on cosmic string network evolution
J. R. C. C. C. Correia, C. J. A. P. Martins
Quantitative studies of the evolution and cosmological consequences of networks of cosmic strings (or other topological defects) require a combination of numerical simulations and…
Abelian-Higgs cosmic string evolution with multiple GPUs
J. R. C. C. C. Correia, C. J. A. P. Martins
Topological defects form at cosmological phase transitions by the Kibble mechanism. Cosmic strings and superstrings can lead to particularly interesting astrophysical and cosmologi…
Extending and Calibrating the Velocity dependent One-Scale model for Cosmic Strings with One Thousand Field Theory Simulations
J. R. C. C. C. Correia, C. J. A. P. Martins
Understanding the evolution and cosmological consequences of topological defect networks requires a combination of analytic modeling and numerical simulations. The canonical analyt…
Abelian-Higgs Cosmic String Evolution with CUDA
J. R. C. C. C. Correia, C. J. A. P. Martins
Topological defects form at cosmological phase transitions by the Kibble mechanism, with cosmic strings and superstrings having the most interesting phenomenology. A rigorous analy…
Effects of biases in domain wall network evolution. II. Quantitative analysis
J. R. C. C. C. Correia, I. S. C. R. Leite, C. J. A. P. Martins
Domain walls form at phase transitions which break discrete symmetries. In a cosmological context they often overclose the universe (contrary to observational evidence), although o…
General purpose graphics-processing-unit implementation of cosmological domain wall network evolution
J. R. C. C. C. Correia, C. J. A. P. Martins
Topological defects unavoidably form at symmetry breaking phase transitions in the early Universe. To probe the parameter space of theoretical models and set tighter experimental c…
Effects of Biases in Domain Wall Network Evolution
J. R. C. C. C. Correia, I. S. C. R. Leite, C. J. A. P. Martins
We study the evolution of various types of biased domain wall networks in the early universe. We carry out larger numerical simulations than currently available in the literature a…
