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. …”

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

Big Bang as a Critical Point by Jakub Mielczarek
