During upconversion photoluminescence in rubrene, four triplet state ions fight it out to release a single high-energy photon. 

A strangely shaped cloud of fermions revealed a record-fast way of cooling atoms for quantum devices.

"Unraveling" cell membrane proteins could help us understand how to build better drugs and treatments for disease.

In the wake of the ongoing coronavirus pandemic, instructors are planning their courses for virtual platforms—a major challenge for laboratory classes. JILA Fellow Heather Lewandowski has gathered some helpful tools for those teaching physics…

Using the laser from the strontium optical atomic clock, physicists can generate multiple cat-state atoms quickly and easily.

Electronics keep shrinking. As they shrink the properties of the materials that make them change too. 

Within our solar system are icy planetary bodies that do not orbit the Sun. JILA Fellow Ann Marie Madigan's group suggest that these detached objects have steadily nudged themselves out of solar orbit over millions of years.

Bringing molecules down to ultracold temperatures takes a mythic approach, but the Ye Group finds that their new scheme can hold up under tough conditions.

The secrets of nature are written in nanoscale. Now the Raschke Group has found a way to read those secrets.

The world is out-of-equilibrium, and JILA scientists are trying to learn what rules govern the dynamic systems that make our universe so complex and beautiful, from black holes to our living bodies.

In a new study from the Kapteyn-Murnane Group, ultrafast laser pulses can precisely cut through and manipulate the interaction between electrons and phonons in tantalum diselenide, changing its properties.

Could quantum entanglement improve our cell phone networks? The Graeme Smith Group at JILA found the answer by playing mathematical logic games.

Quantum technologies could process information even faster if they could harness the speed of light. Using gold nanostars, the Nesbitt Lab have found a way to use light to steer electric currents. 

JILA's Jimenez Lab has developed a flow cytometry systems which take sorting time from days to hours.

Quantum drums can get around distracting noise with a new measurement technique—one that perfectly demonstrates the Heisenberg uncertainty principle.

Atoms could live in their excited states forever by reaching a dark state.

New research from the Cornell Group suggests that the van der Waals universality may have limitations.

How do you hear--and study--the quietest sound in the universe? With a special microphone and speaker. 

An advance from the Raschke group could free quantum technology from ultra-cold temperatures.

Using Feshbach resonance, physicists have found that they can control a dynamical phase transition in an out-of-equilibrium state. 

It's hard to read a clock with hands that wobble. The Ye Group has found a way to steady their optical atomic clock using a new cavity.

While we've known for a while that black holes could rip stars apart, we don’t know why these events occur so frequently. Now, a model by JILA researchers explaining this discrepancy is shown to be promising after passing its first reality test…

It's tough to get tightly-wound balls of DNA to lay down flat and straighten out to get their picture taken. A new technique from the Perkins group gets a crisp, clear picture in just five minutes.

Researchers at JILA and the University of Salamanca have found a new property of light, one that creates a whirling vortex that can speed itself up. 

Getting a cluster state of perfectly entangled atoms for quantum computing may be easier using a tool in JILA's laboratory.

JILA researchers have proposed an experiment that would allow them to study rapid scrambling of quantum information, similar to what happens at the event horizon of a black hole. 

Trapping single atoms is a bit like herding cats, which makes researchers at the University of Colorado Boulder expert feline wranglers. In a new study, a team led by physicist Cindy Regal showed that it could load groups of individual atoms into…
