This paper experimentally demonstrates a new length and alignment control scheme for a 300-meter filter cavity using coherent control sidebands, successfully reducing the cavity's length noise from 6.8 to 2.1 pm to enable frequency-dependent squeezing for advanced gravitational-wave detectors.
The paper introduces SPADE, an autoregressive transformer that independently embeds and delays multi-feature tokens to leverage standard self-attention for learning intra-token correlations, achieving state-of-the-art performance in high-granularity calorimeter shower simulation.
This paper introduces fitPALSpectra, an open-source Python workflow that addresses the challenges of analyzing positron annihilation lifetime spectroscopy (PALS) data by providing a configurable tool for simulating, fitting, and visualizing spectra using an analytically integrated exponential–Gaussian model, which has been validated to accurately recover ground-truth parameters on synthetic data.
This paper characterizes intrinsic and growth-related electrically active defects, specifically identifying the and Nitrogen-related defects, in state-of-the-art n-type 4H Silicon Carbide diodes using Deep-Level Transient Spectroscopy (DLTS) and Thermally Stimulated Currents (TSC) to support the development of radiation-hard sensors for future hadron collider experiments.
The Gain-Layer Project addresses the lack of defect-level understanding regarding radiation-induced degradation in LGADs by producing and characterizing 19,050 specialized silicon diodes with gain-layer-relevant doping concentrations to enable future studies using standard defect spectroscopy techniques.
This paper presents an analytical and finite element analysis demonstrating that commercial high-voltage vacuum feedthroughs often have undersized center conductors leading to excessive electric fields, and proposes a simple, optimized retrofit to mitigate this issue without compromising outgassing properties.
This paper presents the first results from the Eos detector, demonstrating its performance and calibration capabilities using water as a Cherenkov-only medium to validate reconstruction algorithms and detector models for future hybrid neutrino experiments.
This paper introduces "Agentic Hybrid RAG," a framework that combines hybrid retrieval with agentic reasoning to enhance evidence-grounded scientific question answering for muon collider research, validated by a new domain-specific benchmark and superior performance over existing baselines.
This paper demonstrates through simulations and experiments at two research reactors that continuous-signal neutron noise analysis, utilizing pulse-shape deconvolution or detector pairs, effectively overcomes the dead-time and pile-up limitations of traditional pulse-counting to provide unbiased kinetic parameter estimation at high detection rates.
This paper reviews the final decades of the Ohio State University's Big Ear SETI program (1973–1998), highlighting its pioneering role as the first full-time dedicated SETI observatory, its discovery of the famous "Wow! Signal" and other transient events, and the enduring, largely unexplored scientific legacy of its extensive radio sky archives.
