In everyday life, many systems obey simple, linear rules: if you pull twice as hard on a spring, it stretches twice as far. However, when we introduce very large forces or complicated interactions, ...

Quantum teleportation with nonlinear sum frequency generation (SFG). The nonlinear nanophotonic platform greatly mitigates multiphoton noise and leads to high teleportation fidelity. Researchers have ...

“We report on the analysis and design of atomically thin graphene resonant nanoelectromechanical systems (NEMS) that can be engineered to exhibit anharmonicity in the quantum regime. Analysis of ...

Researchers used the nonlinear optical response of atom-like defects in a diamond to build a tiny thermometer. This research may lead to temperature sensors that can work inside living cells and other ...

The team has created an ultrathin metasurface device that boosts nonlinear optical effects at the nanoscale. The advance ...

In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for ...

On the big screen, in video games and in our imaginations, lightsabers flare and catch when they clash together. In reality, as in a laser light show, the beams of light go through each other, ...

On the big screen, in video games and in our imaginations, lightsabers flare and catch when they clash together. That clashing, or interference, happens only in fiction -- and in places with enormous ...
