Exact Green’s Function for 2D Dirac Oscillator in Constant Magnetic Field

in a sufBciently strong magnetic field — where the spin- density waves have a gap — or at half-filling — where the Hubbard model is insulating and the charge excitations are massive

In addition to our measurements of the magnetic moments of a large number of bacteria in various external magnetic fields, we also determined the saturation magnetic moment of

The surface energy of the liquid layer for increasing (open squares) and decreasing (circles) magnetic induction. The full circles mark the increase of E s through the

The Green functions related to a Dirac particle in a constant magnetic field are calculated via two methods, global and local, by using the supersymmetric formalism of Fradkin

The propagator of two-dimensional Dirac oscillator in the presence of a constant magnetic field is presented by means of path integrals, where the spin degree-of-freedom is described

However, mainly in astrophysics [2 – 4], space physics [5, 6], and plasma physics [7,8], there arises very often the problem of the motion of a charged particle when the intensity

We focus our discussion on phases with strong spin-singlet correlations and show that the presence or absence of SU(2) spin rotation symmetry has a clear signature in the full

Those main features all appear in the present analysis such that one can expect that the behavior of the other local dynamical quantities such as the spin-spin correlation function
