# Can the spin cause the collapse?

• I

## Summary:

Solving 1D Dirac equation there are 2 matrixs, and from those we get the space probability and current. If that current reflects the spin state, could happen than the EM fields from the matter acting as potentials, drives the spin to up or down, and when it reaches the north os south pole in bloch sphere, there is the collapse.

## Main Question or Discussion Point

Solving 1D Dirac equation there are 2 matrixs, and from those we get the space probability and current. If that current reflects the spin state, could happen than the EM fields from the matter acting as potentials, drives the spin to up or down, and when it reaches the north os south pole in bloch sphere, there is the collapse.
Not only Like the momentum is atached to the position (it's FFT), I also the current in Dirac equation is a view of it. So if the current matrix is driven to a state that reflects a spin in north or south pole in bloch sphere (like in grover's search ),then we could say that the particle has collapsed?. Also the I suposse that in that case the position matrix must have only one value.
