A low-background setup for in situ X-ray total scattering combined with fast scanning calorimetry [PDF]
Journal of Synchrotron RadiationWe demonstrate a setup, combining fast scanning calorimetry with X-ray total scattering at a synchrotron beamline, allowing for in situ characterizations of the nano-scale structure of samples during and after temperature scans.

Condensate and superfluid fraction of homogeneous Bose gases in a self-consistent Popov approximation [PDF]
Scientific ReportsWe study the condensate and superfluid fraction of a homogeneous gas of weakly interacting bosons in three spatial dimensions by adopting a self-consistent Popov approximation, comparing this approach with other theoretical schemes.

Atomic soliton transmission and induced collapse in scattering from a narrow barrier [PDF]
Scientific ReportsWe report systematic numerical simulations of the collision of a bright matter-wave soliton made of Bose-condensed alkali-metal atoms through a narrow potential barrier by using the three-dimensional Gross–Pitaevskii equation.

The unbearable lightness of charged gravitini
Journal of High Energy Physics, 2021 We prove that charged gravitini cannot have parametrically small or vanishing Lagrangian mass in de Sitter vacua of extended supergravity while respecting the magnetic weak gravity conjecture.

Anti-brane uplift instability from goldstino condensation
Journal of High Energy Physics, 2022 We investigate the possible appearance of composite states of the goldstino in models with four-dimensional non-linear supersymmetry and we provide a description of their dynamics in terms of a Kähler potential and a superpotential.
