Scattering of massless Dirac particles by oscillating barriers in one dimension
We study the scattering of massless Dirac particles by oscillating barriers in one dimension. Using the Floquet theory, we find the exact scattering amplitudes for time-harmonic barriers of arbitrary shape. In all cases the scattering amplitudes are found to be independent of the energy of the incoming particle and the transmission coefficient is unity. This is a manifestation of the Klein tunn...
متن کاملNoncommutative Tsen’s Theorem in Dimension One
Let k be a field. In this paper, we find necessary and sufficient conditions for a noncommutative curve of genus zero over k to be a noncommutative P1-bundle. This result can be considered a noncommutative, onedimensional version of Tsen’s theorem. By specializing this theorem, we show that every arithmetic noncommutative projective line is a noncommutative curve, and conversely we characterize...
متن کاملSelf-Diffusion for Particles with Stochastic Collisions in One Dimension
Color diffusion in a classical fluid composed of two species differing only by color is intimately connected with the asymptotic behavior of trajectories of test particles in the equilibrium system. We investigate here such behavior in a one-dimensional system of "hard" points with density p and velocities _ 1. Colliding particles reflect each other with probability p and pass through each othe...

Levinson's theorem for Dirac particles constraints the sum of the phase shifts at threshold by the total number of bound states of the Dirac equation. Recently , a stronger version of Levinson's theorem has been proven in which the value of the positive-and negative-energy phase shifts are separately constrained by the number of bound states of an appropriate set of Schrödinger-like equations. ...
متن کاملGeneralized Levinson theorem for singular potentials in two dimensions
The Levinson theorem for two-dimensional scattering is generalized for potentials with inverse square singularities. By this theorem, the number of bound states Nm b in a given mth partial wave is related to the phase shift dm(k) and the singularity strength of the potential. When the effective potential has an inverse square singularity at the origin of the form n/r and inverse square tail at ...
