Atomic blockade

Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium.

An international team measures the charge radius of the hydrogen nucleus and stumbles across some mysteries of physics.

In an achievement that could help enable fast quantum computers, University of Michigan physicists have built a better Rydberg atom trap.

Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved.
