This paper proposes a novel algebraic framework for gamma-ray spectroscopy by modeling decay schemes as quivers and introducing a "coincidence algebra bundle" that extends path algebras to calculate coincidence probabilities for non-composable transitions.
This paper introduces a Bayesian protocol that combines full-spectrum template matching with probabilistic evidence evaluation to successfully identify single- and two-source neutron configurations from recoil and time-of-flight spectroscopy data with high statistical significance, even at low event counts.
The Dandelion experiment presents its first results searching for 1 meV dark photon dark matter using a spherical mirror and a 221-KID array, finding no signal and establishing the first millimeter-wavelength upper limits on dark photon kinetic mixing between 0.6 and 1.4 meV after successfully mitigating background noise through de-correlation analysis.
This paper extends previous bounds on the axion-photon coupling by over an order of magnitude using the SACLA X-ray free electron laser and the Borrmann effect in Laue crystals, achieving the most stringent laboratory constraints to date for QCD axions in the 3.46–3.48 keV mass range.
This paper presents an upgraded Trigger and Data Acquisition system for the CYGNO experiment that enables continuous imaging, robust global time-tagging, and synchronized multi-camera operation, establishing a scalable foundation for the upcoming CYGNO-04 phase and future large-scale optical TPC detectors.
This paper presents an upgraded 32 keV angular-selective photoelectron source installed in the KATRIN experiment's beamline in 2022, which enables precise calibration measurements of electron scattering, backscattering, and adiabatic transport through its tunable energy and angle capabilities.
This paper details the measurement and analysis methods used to identify, characterize, and resolve recurrent fault signatures in large-scale stitched CMOS copper metal stacks for the ALICE experiment's MOSS prototype, leading to a successful mitigation strategy implemented by the foundry.
This paper addresses the fabrication challenges of on-chip superconducting integral field units for CMB and line-intensity astronomy by introducing novel components and techniques—including polarization-sensitive crossovers, optimized lithography, dielectric layer deposition, and yield-improving short removal—to successfully fabricate a fourteen-spaxel spectrometer array.
The paper introduces FAlCon, an open-source software ecosystem that addresses the scalability and portability challenges in semiconductor quantum dot experiments by providing a hardware-agnostic domain-specific language, physics-informed data structures, and shared protocols to enable automated, interoperable characterization and tuning workflows across diverse laboratory setups.
This paper introduces a novel molecular dynamics simulation approach that overcomes traditional Lindhard model limitations by incorporating crystal condensed matter effects to accurately predict ultra-low energy ionization yields in semiconductor detectors, thereby extending dark matter exclusion limits to 0.29 GeV/.
