Physical Review A (PRA) provides a dependable resource of worldwide developments in the rapidly evolving areas of atomic, molecular, and optical physics and related fundamental concepts. The journal contains articles on quantum mechanics including quantum information theory, atomic and molecular structure and dynamics, collisions and interactions (including interactions with surfaces and solids), clusters (including fullerenes), atomic and molecular processes in external fields, matter waves (including Bose-Einstein condensation), and optics, both quantum and classical.

Near ground-state cooling of 2-D trapped ion crystals

Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...

Researchers develop new method to reduce quantum noise

In a recent issue of Physical Review A, Argonne researchers reported a new method for alleviating the effects of "noise" in quantum information systems, a challenge scientists around the globe are working to meet in the race ...

Glass fibers and light offer new control over atomic fluorescence

Electrons inside an atom whip around the nucleus like satellites around the Earth, occupying orbits determined by quantum physics. Light can boost an electron to a different, more energetic orbit, but that high doesn't last ...

Research team demonstrates fractal light from lasers

Fractal patterns are common in nature, including in the geometric patterns of a tortoise shell, the structure of a snail shell, the leaves of a succulent plant that repeat to create an intricate pattern, and the frost pattern ...
