Question

What is meant by expectation value?
Explain what is meant by spin-orbit coupling.​

Answer 1

Answer:

According to me about spin-orbit coupling -:

In quantum physics, the spin–orbit interaction (also called spin–orbit effect or spin–orbit coupling) is a relativistic interaction of a particle's spin with its motion inside a potential.The spin–orbit interaction is one cause of magnetocrystalline anisotropy and the spin Hall effect.

Expectation value-:

In quantum mechanics, the expectation value is the probabilistic expected value of the result (measurement) of an experimentIt is a fundamental concept in all areas of quantum physics.
