Spin-1/2 relativistic particle in a magnetic field in NC phase space

【摘要】 This work provides an accurate study of the spin-1/2 relativistic particle in a magnetic field in NC phase space.By detailed calculation we find that the Dirac equation of the relativistic particle in a magnetic field in noncommutative space has similar behaviour to what happens in the Landau problem in commutative space even if an exact map does not exist.By solving the Dirac equation in NC phase space,we not only obtain the energy level of the spin-1/2 relativistic particle in a magnetic field in NC phase space but also explicitly offer some additional terms related to the momentum-momentum non-commutativity.更多还原
