When the Environment Speaks: Quantum Signatures in Non-Attractor Inflation
Mattia Cielo, Simone Scarlatella, Gianpiero Mangano +1
We study the open quantum dynamics of the adiabatic curvature perturbation interacting with a massive entropic scalar environment during an inflationary scenario featuring a transi…
Impact of non-standard neutrino-electron interactions on Big Bang Nucleosynthesis
Stefano Gariazzo, Julien Froustey, Jaume Moncho +2
Neutrino non-standard interactions (NSI) with electrons, predicted in many extended theoretical models of particle physics, are known to alter the picture of neutrino decoupling fr…
Towards Low-Energy Electron High-Resolution Spectroscopy with Transition-Edge Sensors
R. Ammendola, A. Apponi, G. Benato +62
We present a study of the energy resolution of transition-edge sensors (TESs) for the detection of electrons in the 100 eV kinetic energy range. The TES is a Ti-Au bilayer with an…
Ultra-high precision high voltage system for PTOLEMY
R. Ammendola, A. Apponi, G. Benato +63
The PTOLEMY project is prototyping a novel electromagnetic filter for high-precision spectroscopy, with the ultimate and ambitious long-term goal of detecting the cosmic neutr…
Quantum Recoherence in Presence of Excited States in the Early Universe
Mattia Cielo, Simone Scarlatella, Gianpiero Mangano +2
We investigate the quantum-to-classical transition of primordial perturbations within a two-field inflationary framework where an adiabatic mode interacts with an entropic environm…
Current constraints on cosmological scenarios with very low reheating temperatures
Nicola Barbieri, Thejs Brinckmann, Stefano Gariazzo +3
We present a comprehensive analysis of the effects of models with very low reheating scenarios () on the cosmological observables and deri…
