• Evaporation Barrier for Dark Matter in Celestial Bodies Acevedo, J., Leane, R., Smirnov, J. arXiv e-print. 2023 20

  Abstract

  The minimum testable dark matter (DM) mass for almost all DM signatures in celestial bodies is determined by the rate at which DM evaporates. DM evaporation has previously been calculated assuming a competition between the gravitational potential of the object, and thermal kicks from the celestial-body matter. We point out a new effect, where mediators with a range larger than the interparticle spacing induce a force proportional to the density gradient of celestial objects, forming an evaporation barrier for the DM. This effect can be so significant that evaporation does not occur even for sub-MeV DM, in stark contrast to previous calculations. This opens up a wide range of new light DM searches, many orders of magnitude in DM mass below the sensitivity of direct detection.

• Old Rocks, New Limits: Excavated Ancient Mica Searches For Dark Matter Acevedo, J., Bramante, J., Goodman, A. 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 Zarza, G. A., Mangioni, S. E., Fernandez Acevedo, J., Deza, R. R. 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.
