DOI: 10.1007/jhep02(2018)033
Abstract: A bstractWe present simple solutions of IKKT-type matrix models that can be viewed as quantized homogeneous and isotropic cosmological space-times, with finite density of microstates and a regular Big Bang (BB). The BB arises from… read more here.

DOI: 10.1007/jhep02(2020)155
Abstract: We study the chameleon field dark matter, dubbed scalaron , in F ( R ) gravity in the Big Bang Nucleosynthesis (BBN) epoch. With an R 2 -correction term required to solve the singularity problem… read more here.

DOI: 10.1007/s10509-020-3732-8
Abstract: The standard model of cosmology, although very successful, has problems with the very initial phase, such as the existence of a singularity when the density and curvature becomes infinite. In this work we propose a… read more here.

DOI: 10.1007/s10701-018-0162-3
Abstract: The singularity theorems of the 1960s showed that Lemaître’s initial symmetry assumptions were not essential for deriving a big-bang origin for a vast multitude of relativistic universe models. Yet the actual universe accords remarkably closely… read more here.

DOI: 10.1007/s10701-020-00335-7
Abstract: We show that the big bang is a coordinate singularity for a large class of $$k = -1$$k=-1 inflationary FLRW spacetimes which we have dubbed ‘Milne-like.’ By introducing a new set of coordinates, the big… read more here.

DOI: 10.1088/1475-7516/2021/11/017
Abstract: A moving ion in plasma creates a deformed electric potential depending on the ion velocity, which leads to the distinct screening effect compared to the standard static Salpeter formula. In this paper, adopting the test… read more here.
