Domain walls through different cosmologies
I. Dankovsky, D. Gorbunov, S. Ramazanov +1
We study properties of domain walls (DWs) arising in the model with a double well potential assuming different early universe cosmologies: from dust through stiff matter domination…
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…
Lattice simulations of axion-U(1) inflation: gravitational waves, magnetic fields, and scalar statistics
Ramkishor Sharma, Axel Brandenburg, Kandaswamy Subramanian +1
We numerically study axion-U(1) inflation, focusing on the regime where the coupling between axions and gauge fields results in significant backreaction from the amplified gauge fi…
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…
Revisiting evolution of domain walls and their gravitational radiation with CosmoLattice
I. Dankovsky, E. Babichev, D. Gorbunov +2
Employing the publicly available CosmoLattice code, we conduct numerical simulations of a domain wall network and the resulting gravitational waves (GWs) in a radiation-dominated U…
