 pamela
The Space Mission Pamela represents a state-of-the-art of the investigation of the cosmic radiation, addressing the most compelling issues facing astrophysics and cosmology: the nature of the dark matter that pervades the universe, the apparent absence of cosmological antimatter, the origin and evolution of matter in the galaxy.

Cyrogenic dms
The SuperCDMS experiment aims to measure the recoil energy imparted to a nucleus due to collisions with WIMPs by employing detectors which are higly sensitive to the ionization and phonon signals that results from a WIMP-nucleus collision. The detectors, known as iZIP (interleaved Z-sensitive Ionization Phonon) detectors, feature state-of-the-art superconducting thin films deposited on 600g germanium crystals to accurately measure information about the WIMP collisions.

bu experiements
While evidence for dark matter has come from many sources, such as anomalous galactic rotations, the principle evidence for dark matter being a type of exotic, non-baryonic particle comes from Big Bang Nucleosynthesis. Calculations in this model yield specific ratios of light elements in the universe, which are highly sensitive to the distribution and type of matter present. An extension of the standard model, called Supersymmetry (SUSY) offers a promising framework for the type of particle species that could fit the observed properties of dark matter. The most promising candidate particle is the lightest supersymmetric particle (LSP). This is a supersymmetric particle that all other supersymmetric particles would decay into, itself being stable. This particle is called the neutralino Χ01, which is a superposition of the fermionic superpartners of the Higgs and neutral gauge bosons. In order to be consistent with an early universe annihilation rate, leaving proper relic abundances, such a particle should have a small but measurable interaction cross-section with ordinary matter. Specifically a cross-section for interaction between a neutralino and a nucleon in ordinary matter on the order of the electroweak scale would be consistent with a meaningful cosmological role for the particle. This weak interaction cross-section, combined with a mass range of the neutralino between 10 - 100 GeV are what produce the acronym "WIMP". While the cross-section is very small, by virtue of their weak force interaction it should be possible to observe a WIMP by a direct detection experiment that observes collisions with ordinary matter.

the phonon (sound) and ionization signals
SuperCDMS attempts to detect WIMP interactions by observing the phonon (sound) and ionization signals resulting when a WIMP scatters off a nucleus in a detector. A WIMP scatter is expected to deposit energy similar to that of a single x-ray. The primary challenge is WIMP detection is the "needle in a haystack" challenge of distinguishing a WIMP interaction from the millions of times larger background.

Dark Matter via the x-ray emissions
.. cryogenic detectors that operate below 100 mK. ....
Alternately, by turning our field of view outward towards the stars, we search for evidence of Dark Matter via the x-ray emissions from inter-galactic and inter-cluster gas with powerful X-ray telescopes such as the NASA Micro-X mission.

Looking for Hofstadter’s Butterfly in Cold Atoms
Moreover, studying interacting bosons, as opposed to fermions, in Hofstadter bands could reveal unexpected effects. In either case, observing the Hofstadter butterfly directly, or its associated topological state, will require temperatures that are small compared to the gaps between Hofstadter bands. Reaching these temperatures may prove challenging given how much heat the lasers used in the experiments generate. We should emphasize, however, that reaching record low temperatures has been the routine work of cold atom experimentalists.
