Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...

Now, researchers at the University of Chicago Pritzker School of Molecular Engineering and the Abdus Salam International ...

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...

A new study enhances hydrogen molecule predictions, achieving unprecedented precision in testing fundamental physics and ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
