Neural network analysis of neutron and X-ray reflectivity data: Incorporating prior knowledge for tackling the phase problem

Valentin Munteanu, Vladimir Starostin, Alessandro Greco +5

Due to the lack of phase information, determining the physical parameters of multilayer thin films from measured neutron and X-ray reflectivity curves is, on a fundamental level, a…

Probing Axions through Tomography of Anisotropic Cosmic Birefringence

Alessandro Greco, Nicola Bartolo, Alessandro Gruppuso

Cosmic birefringence is the in-vacuo rotation of the linear polarization plane experienced by photons of the Cosmic Microwave Background (CMB) radiation when theoretically well-mot…

Cosmic Birefringence: Cross-Spectra and Cross-Bispectra with CMB Anisotropies

Alessandro Greco, Nicola Bartolo, Alessandro Gruppuso

Parity-violating extensions of Maxwell electromagnetism induce a rotation of the linear polarization plane of photons during propagation. This effect, known as cosmic birefringence…

Measurements of blackbody radiation-induced transition rates between high-lying S, P and D Rydberg levels

Matteo Archimi, Matteo Ceccanti, Marco Distefano +7

We report experimental measurements of the rates of blackbody radiation-induced transitions between high-lying (n>60) S, P and D Rydberg levels of rubidium atoms in a magneto-optic…

Fast Fitting of Reflectivity Data of Growing Thin Films Using Neural Networks

Alessandro Greco, Vladimir Starostin, Christos Karapanagiotis +6

X-ray reflectivity (XRR) is a powerful and popular scattering technique that can give valuable insight into the growth behavior of thin films. In this study, we show how a simple a…
