The quantum-mechanical exchange interaction between electrons, a consequence of the Pauli exclusion principle, can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved ...

Numbers like π, e and φ often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the Riemann zeta function, a ...

Recent advancements in the development of experimental Bell tests have enabled the implementation of a new type of device-independent random number generator. Remarkably, this new type of random number generators can be realized ...
A team of researchers from the U.K., Germany and Russia has used the unpredictable nature of quantum mechanics to create a device capable of generating truly random numbers. In their paper published in the journal Physical ...
Electrons with 'colleagues'—other leptons—are one of many products of collisions observed in the LHCb experiment at the Large Hadron Collider. According to theorists, some of these particles may be created in processes ...

Most physicists believe that the structure of spacetime is formed in an unknown way at the Planck scale, i.e., at a scale close to one trillionth of a trillionth of a metre. However, careful considerations undermine this ...
