(Solved): Spin particle in a magnetic field Given the Hamilton operator: 0 H ==yB - S = G(B; [__]+Bx[]). = + ...

Spin particle in a magnetic field Given the Hamilton operator: 0 H ==yB - S = G(B; [__]+Bx[]). = + Where G - yh 2 And the spin up and down along the z axis: = [0] 08 11> | 1>=60 There is a weak magnetic field along the x-axis and strong magnetic field along the z axis. 1. Use petrubation theory to find the first order correction El to the energies. (Hint: E1 =< [H'll >) 2. Use petrubation theory to find the second order correction Eto the energies.
