Mathematically, quantum mechanical spin is not described by a vector as in classical angular momentum.

Despite the name, particles do not literally spin around an axis, and quantum mechanical spin has no correspondence in classical physics.

Models based on quantum spin describe soap froths as well as magnetic "bubbles" in superconducting films, he said.

Dirac's equation also contributed to explaining the origin of quantum spin as a relativistic phenomenon.

And each branch can have a different quantum spin.

Why is the electron given the quantum spin of +1/2 or -1/2?

The centre puts a quantum spin on a conventional trip to the Mediterranean, giving it focus and shape and heightening the sensations.

Otto Stern and Walther Gerlach establish concept of quantum mechanical spin in subatomic particles.

For instance, quantum mechanical spin can exhibit phenomena analogous to classical gyroscopic effects.

Mathematically, quantum mechanical spin is not described by vectors as in classical angular momentum, but by objects known as spinors.
