A new way to measure the temperatures of objects by studying the effect of their black-body radiation on Rydberg atoms has ...

Key to this study is quantum criticality ... like cosmic microwave background radiation and the radiation of the "black body" that approximates the behavior of stars. This discovery underscores ...

A black body completely absorbs all electromagnetic radiation that ... product of the frequency under consideration and a constant h, today known as Planck’s quantum of action. Planck succeeded in ...

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves ...

Quantum entanglement—a phenomenon where particles are mysteriously linked no matter how far apart they are—presents a long-standing challenge in the physical world, particularly in understanding its ...
