URu2Si2 is a metal that belongs to the family of heavy-fermion compounds in which several quantum phases (e.g., magnetism and superconductivity) can compete or coexist. These metals exhibit small energy scales that are easy ...
Predicted by Einstein's general theory of relativity, gravitational waves are ripples in space-time generated by certain movements of massive objects. They are important to study because they allow us to detect events in ...

Ever tried defrosting your dinner by popping it in one identical freezer after another? Strange as it sounds, recent studies of indefinite causal order—in which different orders of events are quantum superposed—suggest ...
A trio of theoretical physicists at the Pennsylvania State University has calculated the upper limit for the possible quantization of time—they suggest 10−33 seconds as the upper limit for the period of a universal oscillator. ...
Ecole Polytechnique Federale de Lausanne scientists have coupled a new material with light at the level of a single photon. The achievement opens up prospects for better controlling and understanding the properties of quantum-correlated ...
