Spin flip probability of electron due to torsional wave

The probability of spin flip of an electron due to a torsional wave is calculated. It is compared to the electromagnetic case, and ways to detect torsion are discussed.Comment: 6 pages, 1 figur

Spin flip probability of electron in a uniform magnetic field

The probability of a spin flip of an electron is calculated. It is assumed that the electron resides in a uniform magnetic field and interacts with an incoming electromagnetic pulse. The scattering matrix is constructed and the time needed to flip the spin is calculated.Comment: 4 pages, 0 figure
