Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

Researchers have confirmed the existence of a "nuclear-spin dark state," which could lead to more stable and powerful quantum ...

the quantum-mechanical hydrogen atom is stable. If the hydrogen atom obeyed the laws of classical mechanics, by contrast, the electron would spiral into the proton in a tiny fraction of a second ...

Did these researchers truly just crack our fundamental concepts of (quantum) physics wide open ... in the photonic energy getting absorbed by an atom, boosting the energy state of its electron ...

Entropy always increases, but in quantum systems, traditional entropy measures seem constant. TU Wien researchers resolved this paradox by considering Shannon entropy, which accounts for the ...

Quantum materials—those with electronic ... into the TaP crystal—in this case by substituting a hydrogen ion for a tantalum atom—is called doping. And when optimal doping is achieved ...

Conventional quantum mechanics didn't have such transitions ... For example, the electron in a hydrogen atom attracts the proton that is the nucleus, so the effective distance between them ...

A team of physicists affiliated with multiple institutions in China has measured a pulse of light in 37 dimensions. In their ...

Quantum physics underlies technologies from the laser to the smartphone. The International Year of Quantum marks a century of scientific developments.

These were the laws of quantum mechanics, and they got their name from ... Niels Bohr pulled it into his description of how an atom worked. He said that electrons traveling around a nucleus ...
