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 ...

Pseudospin, an additional degree of freedom inherent in graphene, plays a key role in understanding many fundamental phenomena such as the anomalous quantum Hall effect, electron chirality and Klein ...

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 ...

Neutrons, normally thought of as particles, can also be utilized as waves. These waves should, like many other quantum objects, possess a commodity called orbital angular momentum. A new experiment is ...

The uncertainty principle states that we cannot know the state of a system with arbitrary precision. Now the uncertainty relation between angular momentum and position has been measured in an ...

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 ...
