A New Way to Detect Ultra-Light Dark Matter with Millimeter Wave Technology
A new experimental method has been developed that could pave the way for the production of ultra-light dark matter detectors in the form of millimeter-wave receivers. This method, developed by a team of researchers from the University of Pennsylvania and the National Institute of Standards and Technology, uses the properties of an optical cavity to amplify the signals produced by millimeter-wave radiation. The team believes that this technique could be used to create a new type of dark matter detector that would be much more sensitive than existing detectors. The research is still in its early stages, but the team is hopeful that their new method will eventually be used to detect the elusive particles that make up dark matter.
