Sourced fluctuations in generic slow contraction
Michał Artymowski, Ido Ben-Dayan, Udaykrishna Thattarampilly
We introduce a set of generic conditions for the slow contracting Universe and for a narrowed-down category of models called fast-roll models. We present general conditions for sup…
Emergent dark energy from unparticles
Michal Artymowski, Ido Ben-Dayan, Utkarsh Kumar
A limiting temperature of a species can cause the Universe to asymptote to it yielding a deSitter (dS) phase due to macroscopic emergent behavior. The limiting temperature is gener…
Banks-Zaks Cosmology, Inflation, and the Big Bang Singularity
Michal Artymowski, Ido Ben-Dayan, Utkarsh Kumar
We consider the thermodynamical behavior of Banks-Zaks theory close to the conformal point in a cosmological setting. Due to the anomalous dimension, the resulting pressure and ene…
Inflation in supergravity from field redefinitions
Michal Artymowski, Ido Ben-Dayan
Supergravity (SUGRA) theories are specified by a few functions, most notably the real Kähler function denoted by , where K is a real Kähler pot…
Constant roll warm inflation in high dissipative regime
Vahid Kamali, Michał Artymowski, Mohammad Reza Setare
Constant-roll warm inflation is introduced in this work. A novel approach to finding an exact solution for Friedman equations coupled to scalar field equation of motion is presente…
f(R) and Brans-Dicke Theories and the Swampland
Michal Artymowski, Ido Ben-Dayan
We discuss the viability of and Brans-Dicke theories of gravity in light of the recent Swampland conjectures. We show that in the case of perfect fluid domination the swampl…
