a) In a weak magnetic field, broad cyclotron orbits suppress the orbital contribution, allowing spin polarization to dominate, (b) In strong magnetic fields, tight cyclotron orbits enhance orbital ...

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 ...

Vortices of light, null regions of intensity surrounded by spiral phases, makes up the skeleton of a wavefield and influence the properties of light. Since the discovery of the tight connection of ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

A beam transformed: Optical transforms like tight focussing and total internal reflection, which gives rise to an evanescent field, can lead to out-of-plane polarization components and transverse spin ...

It depends on what you mean by rotate. A planet in a locked orbit to its star doesn’t rotate with reference to its star; it rotates once (in essence its day) in the same period as its year (orbital ...
