Gas clouds across the universe are known to absorb the light produced by distant massive celestial objects, known as quasars. This light manifests as the so-called Lyman alpha forest, a dense structure composed of absorption ...
Physicists from TU Delft, ETH Zürich and the University of Tübingen have built a quantum scale heat pump made from particles of light. This device brings scientists closer to the quantum limit of measuring radio frequency ...

Axions and dark photons are two of the most promising types of particles for unveiling new physics. The axion scalar field explains the absence of an electric dipole moment for the neutron, while the dark photon resembles ...
Past cosmological and astrophysical observations suggest that over one quarter of the universe's energy density is made up of a non-conventional type of matter known as dark matter. This type of matter is believed to be composed ...
