The Cosmological Flow: A Systematic Approach to Primordial Correlators
Lucas Pinol, Sébastien Renaux-Petel, Denis Werth
The time evolution of primordial fluctuations conceals a wealth of insights into the high-energy physics at play during the earliest moments of our Universe, which is ultimately en…
Searching for local features in primordial power spectrum using genetic algorithms
Kushal Lodha, Lucas Pinol, Savvas Nesseris +3
We present a novel methodology for exploring local features directly in the primordial power spectrum using a genetic algorithm (GA) pipeline coupled with a Boltzmann solver and Co…
Borel resummation of secular divergences in stochastic inflation
Masazumi Honda, Ryusuke Jinno, Lucas Pinol +1
We make use of Borel resummation to extract the exact time dependence from the divergent series found in the context of stochastic inflation. Correlation functions of self-interact…
Primordial Gravitational Waves in non-Minimally Coupled Chromo-Natural Inflation
Ema Dimastrogiovanni, Matteo Fasiello, Martino Michelotti +1
We consider inflation driven by an axion-like particle coupled to an SU(2) gauge sector via a Chern-Simons term. Known as chromo-natural inflation, this scenario is in tension with…
Cosmological Flow of Primordial Correlators
Denis Werth, Lucas Pinol, Sébastien Renaux-Petel
Correlation functions of primordial density fluctuations provide an exciting probe of the physics governing the earliest moments of our Universe. However, the standard approach to…
