Old Rocks, New Limits: Excavated Ancient Mica Searches For Dark Matter
arXiv e-print.
2021
21 pages, 4 figures
Abstract
Minerals excavated from the Earth's crust contain gigayear-long astroparticle records, which can be read out using acid etching and microscopy, providing unmatched sensitivity to high mass dark matter. A roughly millimetre size slab of 500 million year old muscovite mica, calibrated and analyzed by Snowden-Ifft et al.~in 1990, revealed no signs of dark matter recoils and placed competitive limits on the nuclear interactions for sub-TeV mass dark matter. A different analysis of larger mica slabs in 1986 by Price and Salamon searched for strongly interacting monopoles. After implementing a detailed treatment of Earth's overburden, we utilize these ancient etched mica data to obtain new bounds on high mass dark matter interactions with nuclei.

Limiting the stroke of a Schmitt trigger with multiplicative noise
PHYSICAL REVIEW E
2017; 95 (5): 052143
Abstract
We have devised an experiment whereby a bistable system is confined away from its deterministic attractors by means of multiplicative noise. Together with previous numerical results, our experimental results validate the hypothesis that the higher the slope of the noise's multiplicative factor, the more it shifts the stationary states.
