Gravitational-wave lensing beyond rays: a disordered-system approach
Ripalta Amoruso, Ginevra Braga, Alice Garoffolo +3
We develop a framework to describe gravitational wave propagation through a stochastic distribution of weak gravitational lenses beyond the geometric optics limit. We model the len…

Quantum signatures and decoherence during inflation from deep subhorizon perturbations
Francescopaolo Lopez, Nicola Bartolo
In order to shed light on the quantum-to-classical transition of the primordial perturbations in single field inflation, we investigate the decoherence and associated quantum corre…
