Thermalization effects on the dynamics of growing vacuum bubbles
Tomasz Krajewski, Marek Lewicki, Martin Vasar +3
We study the evolution of growing vacuum bubbles. The bubble walls interact with the surrounding fluid and may, consequently, reach a terminal velocity. If the mean free path of th…
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…
Double scaling limit of the prismatic tensor model
T. Krajewski, T. Muller, A. Tanasa
In S. Giombi, I. Klebanov, F. Popov, S. Prakash and G. Tarnopolsky, {\it Phys. Rev.} {\bf D} 98 (2018) 10, 105005, a prismatic tensor model was introduced. We study here the diagra…
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…
Higgs domain walls in the thermal background
Tomasz Krajewski, Zygmunt Lalak, Marek Lewicki +1
Most cosmological models predict that the universe was hot and dense at the early stages of it's evolution. In this paper we analyse the influence of the thermal bath of Standard M…
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 in the extensions of the Standard Model
Tomasz Krajewski, Zygmunt Lalak, Marek Lewicki +1
Our main interest is the evolution of domain walls of the Higgs field in the early Universe. The aim of this paper is to understand how dynamics of Higgs domain walls could be infl…
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…
Naturalness of effective theories in Wilsonian approach
Tomasz Krajewski, Zygmunt Lalak
We have computed Wilsonian effective action in a simple model containing scalar field with quartic self-coupling which interacts via Yukawa coupling with a Dirac fermion. The model…
Fine-tuning and vacuum stability in Wilsonian effective action
Tomasz Krajewski, Zygmunt Lalak
We have computed Wilsonian effective action in a simple model containing scalar field with quartic self-coupling which interacts via Yukawa coupling with a Dirac fermion. The model…
