Defect junctions and domain wall dynamics

Abstract: 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 defect networks with junctions. Understanding these mechanisms is vital for a proper assessment of a number of cosmological scenarios: we will focus on the issue of whether or not cosmological frustrated domain wall networks can exist at all, but our results are also relevant for the dynamics of cosmic (super)strings, where junctions are… Show more

“…We are considering dimensionless variables, that is, we have rescaled both the fields and the space and time coordinates appropriately such that they are now dimensionless quantities. If ε = 0 then the fields, φ and χ, are not coupled and the minima of the potential are at v [11,13] for more details).…”

“…They are, however, often overlooked in cosmology since the energy scale of the phase transition that originates the domain walls is restricted to be smaller than 1 MeV [2]. Nonetheless, there is still room for domain walls to play a relevant role in cosmology: for instance, they have been suggested as a possible significant dark energy contributor [3]-albeit they have since been ruled out as a major dark energy component [4][5][6] -and as a possible explanation for the spatial variations of the fine structure constant hinted at by HIRES/Keck and VLT/UVES data [7][8][9].…”
