A promising technology concept for sub-GeV dark matter detection is described, in which
low-temperature microcalorimeters serve as the sensors and superfluid He 4 serves as the …

The focus of dark matter searches to date has been on Weakly Interacting Massive Particles
(WIMPs) in the GeV/c 2-TeV/c 2 mass range. The direct, indirect and collider searches in this …

A cryogenic apparatus is described that enables a new experiment, nEDM@ SNS, with a
major improvement in sensitivity compared to the existing limit in the search for a neutron …

Direct searches for light dark matter particles (mass< 10 GeV) are especially challenging
because of the low energies transferred in elastic scattering to typical heavy nuclear targets …

Dark matter (DM) is one of the most critical questions to be understood and answered in
fundamental physics today. Observations with varied astronomical and cosmological …

A bstract We explore the possibility of using superfluid helium for direct detection of sub-GeV
dark matter (DM). We discuss the relevant phenomenology resulting from the scattering of …

The scintillation properties of liquid helium upon the recoil of a low-energy helium atom are
discussed in the context of the possible use of this medium as a detector of dark matter. It is …

We have constructed an apparatus to study DC electrical breakdown in liquid helium at
temperatures as low as 0.4 K and at pressures between the saturated vapor pressure and∼ …

Novel experimental techniques are required to make the next big leap in neutron electric
dipole moment experimental sensitivity, both in terms of statistics and systematic error …

Time dependent observations of point-to-point correlations of the velocity vector field
(structure functions) are necessary to model and understand fluid flow around complex …
