Scaling of cosmological domain wall networks with junctions
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We describe the results of the largest and most accurate three-dimensional field theory simulations of domain wall networks with junctions. We consider a previously introduced clas…
Defect Junctions and Domain Wall Dynamics
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We study a number of domain wall forming models where various types of defect junctions can exist. These illustrate some of the mechanisms that will determine the evolution of defe…
Frustrated Expectations: Defect Networks and Dark Energy
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We discuss necessary conditions for a network of cosmic domain walls to have a chance of providing the dark energy that might explain the recent acceleration of the universe. We de…
Gravitational Effects of Varying Alpha Strings
J. Menezes, P. P. Avelino, C. Santos
We study spatial variations of the fine-structure constant in the presence of static straight cosmic strings in the weak-field approximation in Einstein gravity. We work in the con…
