Parameter-free velocity-dependent one-scale model for domain walls

Parameter-free velocity-dependent one-scale model for domain walls

We develop a parameter-free velocity-dependent one-scale model for the evolution of the characteristic length L and root-mean-square velocity σv of standard domain wall networks in homogeneous and isotropic cosmologies. We compare the frictionless scaling solutions predicted by our model, in the con...

Zusammenfassung:We develop a parameter-free velocity-dependent one-scale model for the evolution of the characteristic length L and root-mean-square velocity σv of standard domain wall networks in homogeneous and isotropic cosmologies. We compare the frictionless scaling solutions predicted by our model, in the context of cosmological models having a power law evolution of the scale factor a as a function of the cosmic time t (a∝tλ, 0
