Modeling Ultracold Molecular Collisions

Two theorists have devised a simple, widely applicable model1 for characterizing the ways in which ultracold molecules interact under a range of conditions, improving researchers' ability to control, measure and understand phenomena in one of the most exciting fields of modern physics.

Soliton in Ultracold Gases

Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but JQI theoreticians and colleagues in India and the George Mason University now believe that there may be a new kind of soliton that’s even more special.

Synthetic Magnetism Achieved by Optical Methods in Ultracold Atoms

For the first time, physicists have used laser light to create "synthetic magnetism," an exotic condition in which neutral atoms suddenly begin to behave as if they were charged particles interacting with a magnetic field -- even though no such field is present and the atoms have no charge.

Entangled Photons from Quantum Dots

To exploit the quantum world to the fullest, a key commodity is entanglement—the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another.

Controlling Trapped Atoms with RF

Investigating mysterious data in ultracold gases of rubidium atoms, scientists at the Joint Quantum Institute and collaborators have found that properly tuned radio-frequency waves can influence how much the atoms attract or repel one another, opening up new ways to control their interactions.

Diamond Sparkle as Quantum Information

Researchers have devised a means of dramatically increasing the fidelity of key quantum measurements in diamond crystal, a development that could lead to the creation of high-resolution magnetic sensors and to powerful new techniques for quantum computation.

Benefits of Frustration

Scientists have demonstrated a new way to control quantum interactions that makes it possible to fine-tune the way in which the magnetic properties of trapped atoms couple to, and are "entangled" with, those of their neighbors -- a development with potentially important applications in quantum computing and condensed-matter simulations.
