Searches for New Particles Including Dark Matter with Atomic, Molecular and Optical Systems

, 2018
New particles can manifest their effects in many settings, ranging from effects on sub-atomic to galactic length scales. The nature of these effects depends on the specific particles and their non-gravitational interactions.

HaloScope: Harnessing Unlabeled LLM Generations for Hallucination Detection

Advances in Neural Information Processing Systems 37
The surge in applications of large language models (LLMs) has prompted concerns about the generation of misleading or fabricated information, known as hallucinations. Therefore, detecting hallucinations has become critical to maintaining trust in LLM-generated content.

Prospects for detection of ultra high frequency gravitational waves from compact binary coalescences with resonant cavities

European Physical Journal C: Particles and Fields
This article aims at clarifying the situation about astrophysical sources that might be observed with haloscope experiments sensitive to gravitational waves in the 1–10 GHz band. The GrAHal setup is taken as a benchmark. We follow a very pedagogical path

Practical photonic bandgap structures for high frequency axion haloscopes

Review of Scientific Instruments
Current and future searches for dark matter axions, based on their resonant conversion to photons in a magnetic field, span many orders of magnitude. A major impediment to designing resonators at the high end of this range, 5 GHz and above, is the proliferation of TE modes, which overwhelm and hybridize with the TM010 mode to which the axion couples ...

Axion Haloscopes with Toroidal Geometry at CAPP/IBS

, 2016
\hspace{3ex} The present state of the art axion haloscope employs a cylindrical resonant cavity in a solenoidal field. We, the Center for Axion and Precision Physics Research (CAPP) of the Institute for Basic Science (IBS) in Korea, are also pursuing halo axion discovery using this cylindrical geometry.
