Assuming dark matter exists, its interactions with ordinary matter are so subtle that even the most sensitive instruments cannot detect them. In a new study, Northwestern University physicists now ...
The study, "Polaronic polariton quasiparticles in a dark excitonic medium," was published in Physical Review B. Exciton-polaritons (polaritons, for short) are hybrid mixtures of light and matter ...
Scientists have not yet observed dark matter directly. It doesn't interact with baryonic matter and it's completely invisible to light and other forms of electromagnetic radiation, making dark ...
