Quantum Brownian Motion: proving that the Schmid transition belongs to the Berezinskii-Kosterlitz-Thouless universality class
Francesco G. Capone, Antonio de Candia, Vittorio Cataudella +4
We investigate the equilibrium properties of a quantum Brownian particle moving in a periodic potential, specifically addressing the nature of the dissipation-driven Schmid transit…
Quantum vs thermal fluctuations in phase transitions of two-dimensional superconductors
Andrea Ponticelli, Francesco Giuseppe Capone, Vittorio Cataudella +3
We investigate the impact of quantum and thermal phase fluctuations on the suppression of superconducting order in two-dimensional systems. Within the two-dimensional quantum XY mo…
DenseRec: Revisiting Dense Content Embeddings for Sequential Transformer-based Recommendation
Jan Malte Lichtenberg, Antonio De Candia, Matteo Ruffini
Transformer-based sequential recommenders, such as SASRec or BERT4Rec, typically rely solely on learned item ID embeddings, making them vulnerable to the item cold-start problem, p…
Characterization of spurious-electron signals in the double-phase argon TPC of the DarkSide-50 experiment
50 Collaboration, P. Agnes, I. F. Albuquerque +144
Spurious-electron signals in dual-phase noble-liquid time projection chambers have been observed in both xenon and argon Time Projection Chambers (TPCs). This paper presents the fi…
A Clue on Small-Capacitance Josephson Junction: What to Expect from Cooper Pair Ideal Conductor and Ohmic Resistor in Parallel?
Francesco Giuseppe Capone, Antonio de Candia, Vittorio Cataudella +3
By using analytical and Worldline Monte Carlo approaches, we investigate the effects induced by quantum phase fluctuations combined with quasiparticle subgap and shunt resistances…
Search for dark matter annual modulation with DarkSide-50
50 Collaboration, P. Agnes, I. F. M. Albuquerque +142
Dark matter induced event rate in an Earth-based detector is predicted to show an annual modulation as a result of the Earth's orbital motion around the Sun. We searched for this m…
