When a magnetic material like nickel is zapped with an incredibly short laser pulse, it loses its magnetism almost instantly within femtoseconds, or a millionth of a billionth of a second. But physics ...

Atomic spins set quantum fluid in motion: Experimental realization of the Einstein–de Haas effect
The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...
In the beam of light emitted by a laser pointer, photons travel predominantly along one direction and the beam is therefore said to be collimated. The electric field carried by these photons is ...
In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...
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 ...
The Einstein-de Haas effect has been observed in a quantum fluid, showing that changes in magnetization transfer angular ...
New research by an astrophysicist provides revelations about the most energetic event in the universe -- the merging of two spinning, orbiting black holes into a much larger black hole. New research ...
Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...
