The fact that light carries both linear and angular momentum is well-known to physicists. One application of the linear momentum of light is for optical tweezers, in which the refraction of a laser ...

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 ...

Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...

This is a preview. Log in through your library . Abstract Entanglement of the properties of two separated particles constitutes a fundamental signature of quantum mechanics and is a key resource for ...

Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...

Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown 1. This will help to provide new insights ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Subscribe to our newsletter for the latest ...

Electrons are proficient little magicians. They seem to flit about an atom without tracing a particular path, they frequently appear to be in two places at once, and their behavior in silicon ...

Complex cyclic changes in many Earth systems (sea level, climate, geomagnetic intensity, etc.) appear to be systematic and triggered exogenetically in the Solar System. Calculations of the changes in ...
