How ultracold, superdense atoms become invisible

An atom’s electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli exclusion principle, and it explains the shell structure of atoms, the diversity...

Collaborations with Minority-Serving Institutions

The CUA is welcoming suggestions for collaborative research with minority-serving institutions. Under the new NSF PREP program, aimed at increasing participation of members from underrepresented groups in physics, we are actively seeking proposals for new collaborations. Please contact Professor Vladan Vuletic to discuss establishing a collaboration under the PREP program. For full proposal details, please...

‘Spooky action at a distance’ could create a nearly perfect clock

Physicists imagine a day when they will be able to design a clock that’s so precise, it will be used to detect subtle disturbances in space-time or to find the elusive dark matter that tugs on everything yet emits no light. The ticking of this clock will be almost perfect. That dream may not be far off:...

New type of atomic clock keeps time even more precisely

Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in sync. The best atomic clocks in the world keep time with such precision that, if they had been running since the beginning...

Researchers observe what could be the first hints of dark bosons

Extremely light and weakly interacting particles may play a crucial role in cosmology and in the ongoing search for dark matter. Unfortunately, however, these particles have so far proved very difficult to detect using existing high-energy colliders. Researchers worldwide have thus been trying to develop alternative technologies and methods that could enable the detection of...

New phase transition in the standard model of quantum optics

Proposed in 1954 by Robert H. Dicke, the Dicke `spin-boson’ model is among the most successful paradigms to describe the interaction of light and matter. Modeling the coupling of an ensemble of spins or atoms to a harmonic oscillator, it is thus sometimes referred to as the “standard model of quantum optics.” As discovered in...
