Laser cooling and trapping allow physicists to map the dynamics of every ion-atom encounter in a collision experiment. For many years atomic-collision experiments basically involved measuring the ...

Heavy duty A high-energy photonic jet (white and blue) blasts through a collapsing star with a black hole at its centre. The cocoon where free neutrons may be available for the r-process is shown in ...

Rubidium atoms can behave unpredictably during atomic collisions, especially when exposed to specific laser light. Researchers have now discovered that these tiny interactions can release unexpected ...

At ultracold temperatures, interatomic collisions are relatively simple, and their outcome can be controlled using a magnetic field. However, research by scientists led by Prof. Michal Tomza from the ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

Why do we live in a universe with three dimensions of space and one of time—3+1 dimensions, as cosmologists would say? Why not some other combination, such as four dimensions of space or two ...

A new biography of Luis Alvarez captures the details but misses the drama in the career of a scientist whose work ranged from the Manhattan Project to the death of the dinosaurs. By Jennifer Szalai ...

Ultrathin materials such as graphene promise a revolution in nanoscience and technology. Researchers have now made an important advance within the field. In a recent article they present a method for ...
