Say an electron tunnels from one state, through a tunneling barrier, to another state.
Is the spin of that electron preserved (the same before and after)?
If an electron is traveling through a bulk phase conductive metal (a wire), is its spin stable in one state? What will happen to its spin when it hits a scattering site (impurity or crystal defect)?
Is there such a thing as a coherence length - the average length an electron will travel without its spin changing or relaxing? Is this related to the localization length of the electron or the mean free path?
Thanks
