SiPM-matrix readout of two-phase argon detectors using electroluminescence in the visible and near infrared range
The DarkSide collaboration, C. E. Aalseth, S. Abdelhakim +312
Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter searches to record (in the gas phase) the ionization signal induced by particle…
Design and construction of a new detector to measure ultra-low radioactive-isotope contamination of argon
The DarkSide Collaboration, C. E. Aalseth, S. Abdelhakim +328
Large liquid argon detectors offer one of the best avenues for the detection of galactic weakly interacting massive particles (WIMPs) via their scattering on atomic nuclei. The liq…
Scaling-up Simulations of Diffusion in Microporous Materials
Giovanni Pireddu, Federico G. Pazzona, Pierfranco Demontis +1
We introduce and demonstrate the coarse-graining of static and dynamical properties of host-guest systems constituted by methane in two different microporous materials. The referen…
Spatial coarse-graining of methane adsorption in graphene materials
Giovanni Pireddu, Federico G. Pazzona, Alberto M. Pintus +2
We investigate the spatial coarse-graining of interactions in host-guest systems within the framework of the recently proposed Interacting Pair Approximation (IPA). Basically, the…
Molecular QCA embedding in microporous materials
Alberto M. Pintus, Andrea Gabrieli, Federico G. Pazzona +2
We propose a new environment for information encoding and transmission via a novel type of molecular Quantum Dot Cellular Automata (QCA) wire, composed of a single row of head-to-t…
Constraints on Sub-GeV Dark Matter-Electron Scattering from the DarkSide-50 Experiment
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +193
We present new constraints on sub-GeV dark matter particles scattering off electrons in argon based on an analysis of ionization signal data from the DarkSide-50 detector.
