July 03, 2020 - Leonardo Giani (UFES) - O princípio cosmológico, quando e porque
Neste seminário revisarei de maneira pedagógica as motivações teóricas e observacionais por trás de um dos pilares da cosmología moderna, o princípio cosmológico. Em particular tentaremos discutir quando e porque ele se torna uma suposição razoável para a descrição do nosso Universo.
June 26, 2020 - Tays Miranda (UFES) - Colapso estocástico (slides)
Modelos cosmológicos de contração originam flutuações quânticas de vácuo das quais as perturbações primordiais presentes em nosso universo poderiam ser geradas. A existência de uma fase cosmológica antes do Big Bang nos leva a uma perspectiva diferente em relação às condições iniciais para o Universo. Neste seminário, descreveremos um universo em colapso, baseado em um campo escalar com um potencial exponencial, e aplicaremos o formalismo estocástico, o qual nos permite estudar como as flutuações quânticas originam ruídos estocásticos que modificam a dinâmica clássica do campo escalar em largas escalas, acima de uma escala de corte que chamamos de coarse-graining scale. Em particular, vamos explorar como essas flutuações quânticas podem perturbar a equação de estado em largas escalas levando à violação da solução clássica de colapso.
June 19, 2020 - Davi Rodrigues (UFES) - General relativity with running couplings and cosmological implications (slides)
There are currently different frameworks for gravity with running couplings. I will comment on some of them and present our recent results, which are based on possible renormalization group (RG) effects at large scales. Our approach has two key differences with respect to other RG approaches that consider large distances phenomena: i) it is explicitly described by a covariant effective action that contains all the relevant information; ii) the runnings of G and \Lambda are sensitive to the wavenumber k from the cosmological perturbations, not the Hubble parameter or the time since the big bang (as the majority of the approaches consider). Consequently, in this picture, the background evolution is essentially the same of LCDM, the new effects are in the perturbative sector. To disclose its consequences, we evaluate its PPF parameters and f\sigma_8. We comment about a possible impact on alleviating the \sigma_8 tension found in LCDM cosmology. A complete CMB analysis with Class and Monte Python is under evaluation.
June 12, 2020 - Saulo Carneiro (UFBA) - On the value of the Immirzi parameter and the horizon entropy
The absence of driving experimental tests is one of the main challenges for quantum gravity theories. In Loop Quantum Gravity (LQG) the quantisation of General Relativity leads to precise predictions for the eigenvalues of geometrical observables like volume and area, up to the value of the only free parameter in the theory, the Barbero-Immirzi (BI) parameter. With the help of the eigenvalues equation for the area operator, LQG successfully derives the Bekenstein-Hawking entropy of large black holes with isolated horizons, fixing in this limit the BI parameter as γ ≈ 0.274. Any further empirical test should give this same value. In this paper we show that a black hole with angular momentum J =1 and Planck mass is eigenstate of the area operator provided that γ = √3/6 ≈ 1.05 × 0.274. As the black hole is extremal, there is no Hawking radiation and the horizon is isolated. We then show that such a black hole can be formed in the head-on scattering of two parallel Standard Model neutrinos in the mass state m2 (assuming m1 = 0). Furthermore, we use the obtained BI parameter to numerically compute the entropy of isolated horizons with areas ranging up to 250 lP2 , by counting the number of micro-states associated to a given area. The resulting entropy has a leading term S ≈ 0.25 A, in agreement to the Bekenstein-Hawking entropy.
June 5, 2020 - Olesya Galkina (UFES) - Future soft singularities, Born-Infeld-like fields and particles (slides).
We consider different scenarios of the evolution of the universe, where the singularities or some non-analyticities in the geometry of the spacetime are present, trying to answer the following question: is it possible to conserve some kind of notion of particle corresponding to a chosen quantum field present in the universe when the latter approaches the singularity? We study scalar fields with different types of Lagrangians, writing down the second-order differential equations for the linear perturbations of these fields in the vicinity of a singularity. If at least one of two independent solutions has a singular asymptotic behavior, then we cannot define the creation and the annihilation operators and construct the vacuum and the Fock space. This means that the very notion of particle loses sense. In the case of the model of the universe described by the tachyon field with a special trigonometric potential, where the Big Brake singularity occurs, we see that the (pseudo)
tachyon particles do not pass through this singularity. Adding to this model some quantity of dust, we slightly change the characteristics of this singularity and tachyon particles survive. Finally, we consider a model with the scalar field with the cusped potential, where the phantom divide line crossing occurs. Here the particles are well defined in the vicinity of this crossing point.
March 20, 2020 - CANCELED due to COVID19- Tays Miranda de Andrade (UFES) - Stochastic formalism applied to a collapsing universe
Contracting cosmologies give rise to quantum vacuum fluctuations from which the primordial perturbations present in our universe could be generated. The existence of a cosmological phase before the Big Bang leads to a different perspective regarding the initial conditions for the universe. In this talk I will describe a collapsing universe, based on a scalar field and an exponential potential, and apply the stochastic formalism, which allows us to study how quantum fluctuations give rise to stochastic noise which modifies the classical dynamics of the scalar field at large scales, above a coarse-graining scale. In particular I will explore how quantum fluctuations can perturb the equation of state on large scales leading to the break down of the classical collapse solution.
