When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

Scientists identify two sound-driven mechanisms for generating orbital currents, merging acoustics with cutting-edge electron ...

In a closed physical system, the sum of all angular momentum remains constant – says an important physical law of conservation. Angular momentum does not necessarily need to involve "real" bodily ...

Ultrashort measurement-time resolution is traditionally obtained in pump–probe experiments, for which two ultrashort light pulses are required; the time resolution is then determined by the pulse ...

Optical vortices are currently one of the most intensively studied topics in optics. These light beams, which carry orbital angular momentum (OAM), have been successfully utilized in the visible and ...

A chemical reaction can be understood in detail at the quantum state-resolved level, through a combined study of molecular crossed beam experiments and theoretical quantum molecular reaction dynamics ...

Yes. I just posted about MythBusters. However, I thought this would be an appropriate time to also talk about the physics involved with the "shoot the merry go round" myth. The basic idea of the myth ...

The most common way to form a black hole in the Universe is to have a massive star reach the end of its life and explode in a catastrophic supernova. However, while the outside portions of the star ...
