This paper presents a numerical model of SNSPD absorption that incorporates quantum-corrected optical conductivity of niobium nitride films, demonstrating that the detector's wavelength range is significantly influenced by the material's optical properties rather than solely by its geometric cavity parameters.
This paper outlines the principles, accuracy conditions, and critical importance of Decompositional Electromagnetic Analysis (DEA) as an efficient method for identifying and troubleshooting signal degradation in high-speed digital interconnects operating at data rates up to 224 Gbps.
This paper presents a quantum machine learning approach using rotationally symmetric quanvolutional neural networks to classify track-like and shower-like topologies in LArTPC neutrino events, finding that while these quantum models outperform similarly sized classical networks, they are ultimately surpassed by classical models with significantly more parameters.
This paper presents a robust optoelectronic alignment technique for superconducting nanowire single-photon detectors (SNSPDs) that utilizes the temperature-dependent resistivity change induced by optical absorption to achieve sub-micron fiber-to-nanowire coupling precision.
This article reviews recent R&D efforts in Cherenkov imaging technologies, highlighting advances in sensor technology, radiator materials, and photon timing that address growing demands for momentum coverage, precision, and radiation tolerance in future particle and nuclear physics experiments.
This paper proposes a tabletop-scale detector using an amorphous target and phonon sensing to achieve broadband sensitivity for dark photon absorption in the 50–200 meV mass range, potentially surpassing existing constraints by up to two orders of magnitude.
The CYGNO collaboration is advancing a novel gaseous Time Projection Chamber with optical readout to detect light Dark Matter particles, having successfully validated its 3D tracking capabilities with the LIME prototype and now preparing to deploy the scalable 0.4 m³ CYGNO-04 demonstrator in 2026.
This paper presents projected sensitivity estimates showing that the KATRIN experiment, utilizing its upcoming TRISTAN detector upgrade, will be capable of probing keV-scale sterile neutrino mixing amplitudes down to for masses between 4 and 13 keV, significantly extending the reach of previous laboratory searches despite potential systematic uncertainties.
This paper demonstrates that rapid frequency jitter in high-quality resonant systems, such as the Dark SRF experiment, causes minimal power loss, thereby refining dark-photon exclusion bounds to establish world-leading laboratory limits on the photon mass below .
This paper extends Interferometric Particle Imaging (IPI) to characterize small ice crystals down to a few micrometers by combining Phase Field Modelling with Discrete Dipole Approximation simulations, demonstrating that the technique's core principle remains valid for particles as small as 11.5 wavelengths despite the need for wide viewing angles.
