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…
Extending Weinberg's EFT: effective scalar-tensor theories up to sixth order
Eugeny Babichev, Sukŗti Bansal, Maria Mylova +1
We present a systematic construction of the six-derivative effective scalar-tensor theories, extending the four-derivative framework previously developed by Steven Weinberg. The on…
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…
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…
