Analytical calculation of the observational parameters for tachyon inflation
Marko Stojanovic, Neven Bilić, Goran S. Djordjevic +2
We investigate the possibility of analytically calculating observational parameters in tachyon inflation cosmology, using the Hubble expansion rate as a function of the tachyon fie…
Primordial black hole formation in k-inflation models
Neven Bilić, Dragoljub D. Dimitrijević, Goran S. Djordjevic +2
The local primordial density fluctuations caused by quantum vacuum fluctuations during inflation grow into stars and galaxies in the late universe and, if they are large enough, al…
A scaling invariance of the perturbations in -inflation models
Neven Bilić, Dragoljub D. Dimitrijević, Goran S. Djordjevic +2
We study the background and perturbations in -essence inflation models and show that a general -essence exhibits a simple scaling property. In particular, we study two classe…
Terrestrial Very-Long-Baseline Atom Interferometry: Summary of the Second Workshop
Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
Terrestrial Very-Long-Baseline Atom Interferometry: Workshop Summary
Sven Abend, Baptiste Allard, Iván Alonso +250
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world…
Constrained Dynamics of Tachyon Field in FRWL Spacetime
Marko A. Dimitrijević, Dragoljub D. Dimitrijević, Goran Djordjevic +1
In this paper we continue study of tachyon scalar field described by a Dirac-Born-Infeld (DBI) type action with constraints in the cosmological context. The proposed extension of t…
Inflationary RSII Model with a Matter in the Bulk and Exponential Potential of Tachyon Field
Marko Stojanović, Neven Bilić, Dragoljub D. Dimitrijević +2
In this paper we study a tachyon cosmological model based on dynamics of a 3-brane in the second Randall-Sundrum (RSII) model extended to include matter in the bulk. The presence o…
Numerical Calculation of Hubble Hierarchy Parameters and Observational Parameters of Inflation
Milan Milošević, Neven Bilić, Dragoljub D. Dimitrijević +2
We present results obtained by a software we developed for computing observational cosmological inflation parameters: the scalar spectral index () and the tensor-to-scalar rat…
