This paper presents a newly designed, compact Scanning Tunneling Microscope mounted on a rotatable platform that enables high-precision measurements of electronic density of states under vectorial magnetic fields in arbitrary directions, overcoming the directional limitations of conventional STM setups.
This paper presents a single-pulse stimulated Raman photothermal (spSRP) microscopy system that leverages high-peak-power, low-repetition-rate lasers to achieve a 44-fold improvement in detection sensitivity over traditional SRS, enabling high-speed, low-damage imaging of biological samples and the direct visualization of cholesterol-rich membrane domains in live cells.
ImpCresst is a versatile, Geant4-based Monte Carlo simulation tool developed by the CRESST collaboration to model backgrounds and calibration signals in solid-state detectors at keV energies, featuring dynamic CAD-based geometry, advanced particle generators for radionuclides, and a workflow optimized for HPC environments.
This study demonstrates through simulation that orthogonal-strip HPGe detectors, analyzed via a hybrid Geant4-CNN framework, can effectively distinguish neutrinoless double beta decay events from single-electron backgrounds, providing quantitative design guidelines on how strip pitch and crystal thickness impact background rejection efficiency.
The paper introduces DMCPy, a modular Python-based software package designed to streamline data reduction, visualization, and analysis for both powder and single-crystal neutron diffraction experiments conducted on the upgraded DMC diffractometer at SINQ.
This paper presents a novel on-chip superconducting nanomechanical platform that achieves unprecedented parallelism and micro-Pascal pressure resolution, enabling the first high-resolution sensing of Casimir forces across a superconducting transition while effectively suppressing competing environmental effects.
This study evaluates the long-term impact of biofouling and sedimentation on the optical transparency of pathfinder instruments at the Cascadia Basin, revealing significant degradation on upward-facing surfaces over five years while confirming that downward-facing surfaces remain largely unaffected, thereby informing future mitigation strategies for the Pacific Ocean Neutrino Experiment.
This paper introduces AMBER, a segmentation algorithm that leverages the rotational independence of background signals to automatically decompose high-dimensional neutron scattering data into foreground and background contributions, thereby reducing expert input and systematic errors in multiplexing spectrometers.
This paper presents a methodology for characterizing the signal-to-noise ratio of a custom two-photon microscope, compares its performance against commercial systems, and provides a guide for benchmarking similar imaging instruments.
This study demonstrates that doping liquid argon with approximately 2% xenon significantly enhances gas electroluminescence signals by a factor of 2.5 due to efficient energy transfer, a phenomenon characterized through experimental measurements and an analytical model for future low-energy ionization detection applications.
