How longer exciton lifetimes could ease efficiency trade-off in organic solar cells

Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the University of Potsdam, the Paul-Drude-Institut in Berlin

Semiconductor quantum dots 'reawaken' predicted Rabi oscillations, boosting quantum contro

Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called "return" of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first predicted theoretically in 2007, describes the decrease in the emission intensity of

Lithium-doped carbon nanorings show promise for next-generation optical devices

Nonlinear optical materials are essential for advanced photonics and laser technologies, but researchers are still searching for ways to optimize organic, carbon-based alternatives. Using computational modeling, scientists demonstrated that adding a lithium atom to the outside of

Giraffes combine quantities similarly to addition

In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition or subtraction. Now, a study by the University of B

Disorder creates direction-dependent optics in compound semiconductors

An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, their response is averaged over many different local

First-of-a-kind laser spring opens up new avenues for plasma control

When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated a rotating, spring-shaped laser pulse, opening new pos

Physicists demonstrate Hong–Ou–Mandel interference with more than 10 atoms

In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 indistinguishable neutral atoms—an effect that has been predominantly observed in photonic systems.
