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…
Spectral Distortions of the CMB as a Probe of Inflation, Recombination, Structure Formation and Particle Physics
J. Chluba, A. Kogut, S. P. Patil +98
Following the pioneering observations with COBE in the early 1990s, studies of the cosmic microwave background (CMB) have focused on temperature and polarization anisotropies. CMB…
Constraints on Scalar and Tensor spectra from
Ido Ben-Dayan, Brian Keating, David Leon +1
At the linear level, the gravitational wave (GW) spectrum predicted by inflation, and many of its alternatives, can have arbitrarily small amplitude and consequently an unconstrain…
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…
