Nonlocal Quantum Effects in Cosmology by Yurii V. Dumin

“…Since it is commonly believed that the observed large-scale structure of the universe is an imprint of quantum fluctuations existing at the very early stage of its evolution, it is reasonable to pose the question: do the effects of quantum nonlocality, which are well established now by the laboratory studies, manifest themselves also in the early universe? We try to answer this question by utilizing the results of a few experiments, namely, with the superconducting multi-Josephson-junction loops and the ultracold gases in periodic potentials. …”

Do Unusually Cold Starburst Galaxies Exist? A Case Study by Dominik A. Riechers

“…We thus do not find evidence for the existence of unusually cold starburst galaxies in the early Universe that were missed by previous selection techniques.…”

A model of inflation consistent with Planck 2018 and BICEP/Keck data by Li-Yang Chen, Hongwei Yu, Puxun Wu

“…Abstract We establish a phenomenological inflation model in this paper and find that the predicted values of the spectral index and the tensor-to-scalar ratio are well consistent with the results from the Planck 2018 survey and the BICEP/Keck array measurement, significantly improving the theoretical precision in describing the early universe’s inflationary process. After inflation, we find that preheating can occur from the tachyonic instability or the parametric resonance, which depends on the value of one of model parameters.…”

Graviatoms with de Sitter Interior by Irina Dymnikova, Michael Fil’chenkov

“…We estimate probability of formation of RPBHs and G-lumps in the early Universe and evaluate energy spectrum and electromagnetic radiation of graviatom which can in principle bear information about a fundamental symmetry scale responsible for de Sitter interior and serve as its observational signatures.…”

Big Bang as a Critical Point by Jakub Mielczarek

“…This article addresses the issue of possible gravitational phase transitions in the early universe. We suggest that a second-order phase transition observed in the Causal Dynamical Triangulations approach to quantum gravity may have a cosmological relevance. …”

Strong Electroweak Phase Transition in a Model with Extended Scalar Sector by Mina Saeedhosseini, Ali Tofighi

“…Due to this first-order phase transition in the early universe gravitational waves are produced. We estimate the contributions such as the sound wave, the bubble wall collision, and the plasma turbulence to the stochastic gravitational wave background, and we find that the strength at the peak frequency is large enough to be detected at future gravitational interferometers such as eLISA. …”

Early matter domination at colliders: Long live the glueball! by Fady Bishara, Filippo Sala, Kai Schmidt-Hoberg

“…We prove that collider searches for long-lived particles (LLPs) can test the dynamics responsible for matter domination in the early universe. In this letter we concentrate on the specific example of glueballs from a GeV-scale confining dark sector and compute the dilution of cosmological relics induced by their decay. …”

Primordial Dark Energy from a Condensate of Spinors in a 5D Vacuum by Pablo Alejandro Sánchez, Mauricio Bellini

“…We found that the condensate of spinors studied here could be an interesting candidate to explain the presence of dark energy in the early universe. The dark energy density which we are talking about is poured into smaller subhorizon scales with the evolution of the inflationary expansion.…”

Loop quantum effects on direct detection prediction in two-scalar dark matter scenario by Karim Ghorbani, Parsa Ghorbani

“…Among two extra singlet scalars in the two-scalar model, the lighter one is stable and plays the role of dark matter candidate and the heavier one contributes in dark matter co-annihilation processes in thermal history of the early universe. It is already known that the two-scalar model at tree level, unlike the single-scalar dark matter model, can easily evade the bounds from direct detection (DD) experiments. …”

Three-dimensional imaging of topologically protected strings in a multiferroic nanocrystal by Mansoor A. Najeeb, David Serban, Daniel G. Porter, Frank Lichtenberg, Stephen P. Collins, Alessandro Bombardi, Nicola A. Spaldin, Marcus C. Newton

“…Hexagonal manganite multiferroics are of particular interest as the properties of their symmetry-lowering phase transition can be described by a Mexican-hat-like potential energy surface. The early universe is proposed to have undergone a symmetry-lowering phase transition that is described by a similar Mexican-hat-like potential that gives rise to the formation of one-dimensional topologically protected defects known as cosmic strings. …”
