Low-noise Fourier Transform Spectroscopy Enabled by Superconducting On-Chip Filterbank Spectrometers

This paper proposes a hybrid spectroscopic architecture that couples a medium-resolution Fourier transform spectrometer with a low-resolution on-chip filterbank spectrometer to significantly reduce photon noise and enable high-sensitivity, large-field line intensity mapping at resolutions of R~1000 for ground-based and balloon-borne astronomy.

Particle transformers for identifying Lorentz-boosted Higgs bosons decaying to a pair of W bosons

This paper introduces the Particle transformer (PaRT), a novel deep neural network based on self-attention that achieves high-efficiency tagging of Lorentz-boosted Higgs bosons decaying to W boson pairs in CMS data while maintaining decorrelation from jet mass, thereby enhancing the sensitivity of Standard Model measurements and beyond-the-Standard-Model searches.

Neutron Reconstruction via Blips in Liquid Argon Time Projection Chambers

This paper presents a simulation-based proof-of-concept demonstrating that isolated MeV-scale energy deposits ("blips") from neutron inelastic scattering in Liquid Argon Time Projection Chambers can be used to identify and reconstruct the direction and energy of final-state neutrons, thereby enhancing neutrino interaction studies such as neutrino-antineutrino separation.

Development of a Modular Optically Detected Magnetic Resonance Setup for Optical Experiments in a Variable Temperature Insert

The authors present a modular optically detected magnetic resonance (ODMR) setup capable of operating over a two-meter optical path within a commercial helium bath cryostat, successfully demonstrating NV center-based magnetometry and temperature-dependent measurements on samples in constrained cryogenic environments.

In-Situ Performance of FBK VUV-HD3 and HPK VUV4 SiPMs in the LoLX Liquid Xenon Detector

This paper presents a direct in-situ comparison of FBK VUV-HD3 and HPK VUV4 SiPMs within the LoLX liquid xenon detector, revealing that HPK devices detect 33–38% less light than FBK devices under operating conditions and demonstrating that this discrepancy is resolved by an optical simulation incorporating angular and wavelength-dependent surface shadowing effects.

Design, construction, and testing of the PandaX-xT cryogenics system

This paper presents the design, construction, and performance testing of the PandaX-xT cryogenics system, which utilizes two Gifford-McMahon cooling towers and an emergency liquid-nitrogen coil to efficiently manage approximately 43 tons of liquid xenon, achieving a cooling power of about 1900 W at 178 K and maintaining stable pressure fluctuations for a 1-tonne prototype.
