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 ...

Watching, modeling and even playing winter sports help students internalize physics concepts, including acceleration, ...

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 ...

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 ...

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, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

We live and die by data these days. Data rates and latencies are everything, with data centers and chips designed to maximize communication speeds. The hero in the world of data is the optical fiber.

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 ...
