Most of the atomic clocks in the world — fewer than 500 in total — are housed at standards institutes and used to keep time for the planet. But the one inside UC Berkeley’s Kolkowitz Lab has a ...

Researchers at Singapore's Centre for Quantum Technologies have developed a highly accurate lutetium-based atomic clock. This ...

In humankind's ever-ticking pursuit of perfection, scientists have developed an atomic clock that is more precise and accurate than any clock previously created. The new clock was built by researchers ...

Physicists have made one of the highest performance atomic clocks ever. ­­ Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to ...

Results from string theory, generalizing the anti-de Sitter/conformal field theory correspondence, may offer a fresh set of mathematical tools for understanding some kinds of phase transitions that ...

Atomic and molecular physics addresses the structure and interactions of atoms and molecules, uniting quantum theory with experimental observation to explain phenomena from spectral lines to collision ...
