For a spin 1 2 particle placed in a magnetic field B the Hamiltonian is.
In quantum mechanics, spin is an intrinsic property of all elementary particles. Fermions , the particles that constitute ordinary matter, have half-integer spin. All known elementary fermions have a spin of 1 / 2. The behavior of the spin 1/2 system in a magnetic field is interesting experimentally since particle with spin have magnetic dipole moments. This lecture di.

Science; Advanced Physics; Advanced Physics questions and answers; The spin Hamiltonian for a spin 1/2 particle in an external magnetic field is H =- B. Determine the energy eigenvalues exactly and compare with the results of perturbation theory through second order in B2/B0. It is shown that the 22 matrix Hamiltonian describing the dynamics of a charged spin 1/2 particle with g-factor 2 moving in an arbitrary, spatially dependent, magnetic field in two spatial dimensions can be written as the anticommuator of a nilpotent operator and its hermitian conjugate. Consequently, the Hamiltonians for the two different spin projections form partners of a supersymmetric.

The Quantum Hamiltonian Including a B-field. in the usual way, by replacing the momentum by the momentum operator, for the case of a constant magnetic field. Note that the momentum operator will now include momentum in the field, not just the particle#39;s momentum. As this Hamiltonian is written, is the variable conjugate to and is related to the. Present Dirac#x27;s analysis of the magnetic monopole, which leads to an explanation of the quantization of electric charge. 2.

Thus the Hamiltonian for a charged particle in an electric and magnetic field is, #92;[ #92;beginequation H = #92;frac12m#92;left#92;vecp-q#92;vecA#92;right2qV, #92;endequation #92;] The quantity #92;vecp is the conjugate variable to position. It includes a kinetic momentum term and a field momentum term. The intrinsic magnetic moment of a spin- 1 2 particle with charge q, mass m, and spin angular momentum S, is [12] where the dimensionless quantity gs is called the spin g -factor. For exclusively orbital rotations it would be 1 assuming that the mass and the charge occupy spheres of equal radius.
