The BREAD Collaboration is searching for dark photons using a coaxial dish antenna
Approximately 80% of the matter in the universe is predicted to be so-called "dark matter," which does not emit, reflect, or absorb light and thus cannot be directly detected using conventional experimental techniques.
Physicists arrange atoms in close proximity, paving way for exploring exotic states of matter
Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states ...

Twisting and binding matter waves with photons in a cavity
Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it ...
