Simulating the symmetron: domain walls and symmetry-restoring impurities
Jonathan A. Pearson
In this paper we study the dynamics of relativistic domain walls in the presence of static symmetry-restoring impurities. The field theory is precisely the same as what is known to…
Effective action approach to cosmological perturbations in dark energy and modified gravity
Richard A. Battye, Jonathan A. Pearson
In light of upcoming observations modelling perturbations in dark energy and modified gravity models has become an important topic of research. We develop an effective action to co…
X-type and Y-type junction stability in domain wall networks
Richard A. Battye, Jonathan A. Pearson, Adam Moss
We develop an analytic formalism that allows one to quantify the stability properties of X-type and Y-type junctions in domain wall networks in two dimensions. A similar approach m…
Charge, domain walls and dark energy
Jonathan A. Pearson
One idea to explain the mysterious dark energy which appears to pervade the Universe is that it is due to a network of domain walls which has frozen into some kind of static config…
Charge, junctions and the scaling dynamics of domain wall networks
Richard A. Battye, Jonathan A. Pearson
It has been shown that superconducting domain walls in a model with U(1) x Z2 symmetry can form long-lived loops called kinky vortons from random initial conditions in the broken f…
Formation and evolution of kinky vortons
Richard A. Battye, Jonathan A. Pearson, Simon Pike +1
We present field theory simulations of a model with Z_2xU(1) symmetry in (2+1)-dimensions. This model has two discrete vacua, allowing for domain walls, and also a conserved Noethe…
