Steady-state bubbles beyond local thermal equilibrium
Tomasz Krajewski, Marek Lewicki, Ignacy Nałęcz +1
We investigate the hydrodynamic solutions for expanding bubbles in cosmological first-order phase transitions going beyond local thermal equilibrium approximation. Under the assump…
Bubble-wall velocity in local thermal equilibrium: hydrodynamical simulations vs analytical treatment
Tomasz Krajewski, Marek Lewicki, Mateusz Zych
We perform real-time hydrodynamical simulations of the growth of bubbles formed during cosmological first-order phase transitions under the assumption of local thermal equilibrium.…
Hydrodynamical constraints on bubble wall velocity
Tomasz Krajewski, Marek Lewicki, Mateusz Zych
Terminal velocity reached by bubble walls in first order phase transitions is an important parameter determining both primordial gravitational-wave spectrum and production of baryo…
Anatomy of geometrical destabilization of inflation
Tomasz Krajewski, Krzysztof Turzyński
We study geometrical destabilization of inflation with the aim of determining the fate of excited unstable modes. We use numerical lattice simulations to track the dynamics of both…
(P)reheating and gravitational waves in -attractor models
Tomasz Krajewski, Krzysztof Turzyński
We study post-inflationary evolution in -attractor T-models of inflation. We consider the dynamics of both scalar fields present in these models: the inflaton and the spectator,…
Stability of domain walls in models with asymmetric potentials
Tomasz Krajewski, Jan Henryk Kwapisz, Zygmunt Lalak +1
We study the evolution of cosmological domain walls in models with asymmetric potentials. Our research goes beyond the standard case of spontaneous breaking of an approximate symme…
On preheating in alpha-attractor models of inflation
Tomasz Krajewski, Krzysztof Turzyński, Michał Wieczorek
We study (p)reheating in alpha-attractor T-models of inflation, taking into account both scalar fields present in these models: the inflaton and the spectator. The two-field model…
Domain walls and gravitational waves in the Standard Model
Tomasz Krajewski, Zygmunt Lalak, Marek Lewicki +1
We study domain walls which can be created in the Standard Model under the assumption that it is valid up to very high energy scales. We focus on domain walls interpolating between…
