Could a tiny vapor cell make dark matter flicker in laser light?
A proposed chip-scale atomic sensor could turn a hidden-photon dark-matter signal into a faint, readable flicker of laser light.
A Levitated Magnet Listened for Dark Matter Too Heavy to Catch
A levitated milligram magnet searched for ultraheavy dark matter through passing particles’ impulses, turning eight ambiguous kicks into conservative limits.
Could Earth’s Axion Detectors Become a Telescope for Dark Matter?
A proposed network of axion detectors could use signal timing and coherence to map the hidden motion of dark matter near Earth.
