Relation between particle spin with gradient

In summary, the conversation discusses the concept of spin in quantum mechanics and its relation to classical objects. It is mentioned that spin can be approached by gradient and spin values can be described in terms of degrees in a 360 degree space. It is also questioned how spin would be measured for a ball spinning with angular momentum in a non-perpendicular direction. It is noted that there are previous discussions about the misconception that spin is directly linked to the classical spinning of objects.

Can we approach spin by gradient. For example, spin 1/2 can be written as 180 degree turning in 360 degree space while spin 2 is 720 degree turning in 360 degree space?

If I have a ball spinning with angular momentum perpendicular to rotation plane, what is the spin value of the ball? Can some object wobble in the space so the angular momentum is not perpendicular to rotation plane (forming angle)? If that so, what is the spin value of that object?

Please note that there are numerous threads already indicating the myth of the spin quantum number being associated with the classical object spinning. Browse through threads in the quantum physics forum.

FAQ: Relation between particle spin with gradient

1. What is particle spin?

Particle spin is an intrinsic property of subatomic particles, which describes their angular momentum and rotation. It is a quantum mechanical property and can take on only certain discrete values.

2. How is particle spin related to gradient?

Particle spin and gradient are related through the phenomenon of spin-orbit coupling. This is a quantum mechanical interaction between the spin of a particle and its motion in a varying external potential or field, such as a gradient.

3. Can particle spin be affected by gradient?

Yes, particle spin can be affected by gradient through spin-orbit coupling. This interaction can result in changes to the energy levels and other properties of the particle.

4. What is the significance of the relation between particle spin and gradient?

The relation between particle spin and gradient is significant in many areas of physics, including quantum mechanics, solid state physics, and particle physics. It allows for a deeper understanding of the behavior and properties of subatomic particles.

5. How is the relation between particle spin and gradient used in practical applications?

The relation between particle spin and gradient is used in a variety of practical applications, such as in magnetic resonance imaging (MRI) and magnetic data storage. It is also important in the development of new technologies, such as spintronics, which utilize the spin of particles for information processing and storage.
