Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, but they […]
A new analysis of collisions conducted at different energies at the Relativistic Heavy Ion Collider (RHIC) shows tantalizing signs of a critical point — a change in the way that quarks and gluons, the building […]
Engineering researchers report that they developed a new, efficient way to modulate and enhance an important type of nonlinear optical process: optical second harmonic generation — where two input photons are combined in the material […]

Using a new method, physicists are analyzing at the femtosecond scale the processes in a model system for organic solar cells in detail. The results can be used to develop high-performance and efficient solar cells. […]
In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect — a characteristic change in the way electricity is conducted in the presence of a magnetic field — in […]
Scientists aim to numerically investigative the roles of cooperative effects and disorder in photon escape rates from a cold atomic gas to construct a model that considers the vectorial nature of light. Thus, the study […]
