Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

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 ...

What makes something quantum? This question has kept a small but dedicated fraction of the world's population—most of them quantum physicists—up at night for decades. At very small scales, we know the ...

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

In the strange and fascinating world of quantum mechanics, particles have long been sorted into just two types: fermions and bosons. These labels help explain how matter forms and how forces work.

Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, quantum information theory and non-invertible symmetries in particle and ...

An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, ...

What happens when matter transitions from one phase to another—a solid to a liquid or a liquid to a gas? Describing these critical points precisely, in solvable mathematical terms, is no simple feat.
