Atomic, molecular and optical physics lies at the intersection of quantum mechanics and electromagnetic theory, providing the fundamental framework for our understanding of matter and light.

Recent research reveals that quantum mechanics can supersede the second law of thermodynamics at the atomic scale, ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks work, ...

The Nobel Prize in Physics for 2025 honors scaled-up quantum physics—while sidestepping controversies swirling around quantum ...

RICHARD FEYNMAN, one of the 20th century’s greatest physicists, once quipped, “I think I can safely say that nobody understands quantum mechanics.” Appropriately, then, a certain sense of bemusement ...

Prize awarded for developing 'next generation of quantum technology' 'I'm completely stunned,' says UC Berkeley professor Quantum technology ubiquitous in everyday electronics Physics is second prize ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...
