Towards Gravitational Wave Turbulence within the Hadad-Zakharov metric
Benoît Gay, Eugeny Babichev, Sébastien Galtier +1
The theory of gravitational wave turbulence describes the long-term statistical behaviour of a set of weakly nonlinear interacting waves. In this paper, we aim to study aspects of…
Cosmic domain walls on a lattice: illusive effects of initial conditions
I. Dankovsky, S. Ramazanov, E. Babichev +2
Evolution of cosmic domain walls (DWs) settles to the scaling solution, which is often assumed to be independent of initial conditions. However, lattice simulations performed in th…
Biased domain walls: faster annihilation, weaker gravitational waves
E. Babichev, I. Dankovsky, D. Gorbunov +2
We study the evolution of domain wall networks and their phenomenological implications in a model of a real scalar , where a -symmetry is slightly broken by a potential bia…
Numerical analysis of melting domain walls and their gravitational waves
I. Dankovsky, S. Ramazanov, E. Babichev +2
We study domain walls (DWs) arising in field theories where -symmetry is spontaneously broken by a scalar expectation value decreasing proportionally to the Universe temperatu…
