Resumen
We critically review the cosmological EW and QCD phase transitions. The EW and QCD phase transitions would have proceeded dynamically since the expansion of the universe determines the quench rate and critical behaviors at the onset of phase transition slow down the phase transition. We introduce a real-time quench model for dynamical phase transitions and describe the evolution using a canonical real-time formalism. We find the correlation function, the correlation length and time and then discuss the cosmological implications of dynamical phase transitions on EW and QCD phase transitions in

Resumen
Abstract We investigate rarely explored details of supercooled cosmological first-order phase transitions at the electroweak scale, which may lead to strong gravitational wave signals or explain the cosmic baryon asymmetry. The nucleation temperature is often used in phase transition analyses, and is defined through the nucleation condition: on average one bubble has nucleated per Hubble volume. We argue that the nucleation temperature is neither a fundamental nor essential quantity in phase transition analysis. We illustrate scenarios where a transition can complete without satisfying the nuc

Resumen
Abstract Cosmological first order phase transitions are typically associated with physics beyond the Standard Model, and thus of great theoretical and observational interest. Models of phase transitions where the energy is mostly converted to dark radiation can be constrained through limits on the dark radiation energy density (parameterized by ΔN eff). However, the current constraint (ΔN eff < 0.3) assumes the perturbations are adiabatic. We point out that a broad class of non-thermal first order phase transitions that start during inflation but do not complete until after reheating leave

Resumen
Abstract Gravitational wave (GW) predictions of cosmological phase transitions are almost invariably evaluated at either the nucleation or percolation temperature. We investigate the effect of the transition temperature choice on GW predictions, for phase transitions with weak, intermediate and strong supercooling. We find that the peak amplitude of the GW signal varies by a factor of a few for weakly supercooled phase transitions, and by an order of magnitude for strongly supercooled phase transitions. The variation in amplitude for even weakly supercooled phase transitions can be several ord

Resumen
Abstract First-order cosmological phase transitions in the early Universe source sound waves and, subsequently, a background of stochastic gravitational waves. Currently, predictions of these gravitational waves rely heavily on simulations of a Higgs field coupled to the plasma of the early Universe, the former providing the latent heat of the phase transition. Numerically, this is a rather demanding task since several length scales enter the dynamics. From smallest to largest, these are the thickness of the Higgs interface separating the different phases, the shell thickness of the sound wave

Resumen
L'asymétrie entre matière et antimatière est un problème non résolu de la cosmologie. Une approche populaire pour l'expliquer est la leptogénèse avec des neutrinos stériles, qui sont des particules motivées expérimentalement pour expliquer les masses des neutrinos actifs du Modèle Standard. Il est possible d'inclure dans les scénarios de leptogénèse une transition de phase cosmologique qui donne leur masse aux neutrinos stériles. Cette idée est intéressante phénoménologiquement, car une transition de phase produit des ondes gravitationnelles pouvant être détectées. À la température de la trans

Les transitions de phase du premier ordre (PT) dans l'univers primitif se produisent par la nucléation de bulles dont les parois peuvent se dilater à des vitesses ultra-relativistes. Les interactions du bain thermique à la paroi produisent des particules qui s'accumulent dans des coquilles à la paroi. Les coquilles évoluent jusqu'à ce qu'elles entrent en collision avec celles des bulles voisines. Dans cette thèse, nous étudions d'abord l'évolution de ces coquilles, en incluant pour la première fois les interactions de changement de nombre de la coquille à l'intérieur d'elle-même et avec le bai

Resumen
A possible connection between the dark matter and strong first order electroweak phase transition, which is an essential ingredient of the electroweak baryogenesis, has been explored in this thesis. It is shown that the extension of the Standard Model's minimal Higgs sector with an inert $SU(2)_L$ scalar doublet can provide light dark matter candidate and simultaneously induce a strong first order phase transition. There is however no symmetry reason to prevent the extension using scalars with higher $SU(2)_L$ representations. Therefore, by making random scans over the models' paramete

A range of novel ideas, covering both general relativity and quantum field theory are introduced and explored. An analytic procedure for theories that modify the stress-energy-tensor in general relativity is examined which compares predicted deviations in the gravitational wave radiation from binary black hole mergers to the observed waveform from recent detections, i.e GW150914. This is applied directly to the theory of non-commutative spacetimes, which ultimately constrains the scale of non-commutative spacetime up to the Planck scale, some 15 orders of magnitude improvement on previous boun

Resumen
AbstractThis review will be concerned with our knowledge of extended matter under the governance of strong interaction, in short: QCD matter. Strictly speaking, the hadrons are representing the first layer of extended QCD architecture. In fact we encounter the characteristic phenomena of confinement as distances grow to the scale of 1 fm (i.e. hadron size): loss of the chiral symmetry property of the elementary QCD Lagrangian via non-perturbative generation of “massive” quark and gluon condensates, that replace the bare QCD vacuum. However, given such first experiences of transition from short
