General relativistic quantum optics: Finite-size particle detector models in curved spacetimes [PDF]
Physical Review D, 2020 We propose a fully covariant model for smeared particle detectors in quantum field theory in curved spacetimes. We show how effects related to accelerated motion of the detector and the curvature of spacetime influence the way different observers assign ...

Applied Sciences, 2021 On 25 August 2018, a G3-class geomagnetic storm reached the Earth’s magnetosphere, causing a transient rearrangement of the charged particle environment around the planet, which was detected by the High-Energy Particle Detector (HEPD) on board the China ...

Broken covariance of particle detector models in relativistic quantum information [PDF]
Physical Review D, 2020 We show that the predictions of spatially smeared particle detectors coupled to quantum fields are not generally covariant outside the pointlike limit. This lack of covariance manifests itself as an ambiguity in the time-ordering operation.

Design and characterization of a phonon-mediated cryogenic particle detector with an eV-scale threshold and 100 keV-scale dynamic range [PDF]
Physical Review D, 2020 We present the design and characterization of a cryogenic phonon-sensitive 1-gram Si detector exploiting the Neganov-Trofimov-Luke effect to detect single-charge excitations.

Learning representations of irregular particle-detector geometry with distance-weighted graph networks [PDF]
The European Physical Journal C, 2019 We explore the use of graph networks to deal with irregular-geometry detectors in the context of particle reconstruction. Thanks to their representation-learning capabilities, graph networks can exploit the full detector granularity, while natively ...

Experimental studies of QCD using flavour tagged jets with DELPHI [PDF]
, 1996 Identified $b\overline{b}g$ and $q\overline{q}\gamma$ events from DELPHI are used to measure the ratio of the mean charged particle multiplicity distribution between gluon and quark jets.
