The ~inguJanties of the pha~e of an edge ;taie scattered by a barrier interrupting a w ire ii a pei~pendicular magnetic field are di«ussed. The tran;mis,ion properiies Dl such a ~tructure are expres~ed in terms of creation and annihilation of vortex

We study a microjunction in a two-dimensional electron gas under the action of a uniform magnetic field, orthogonal to the gas plane. The microjunction is modeled as an infinite rectilinear waveguide with parabolic walls interrupted by a barrier. Low

La partie spatiale de la fonction d'onde est calculee exactement pour un effet tunnel dans un champ magnetique confine dans une barriere carree epaisse. A cause du champ perpendiculaire au courant, la transmission est fortement reduite et on observe

We solve exactly and numerically the Schrodinger equation when an atom goes towards a metallic surface in the jellium model. The position of the resonance and its width are discussed in varying the screening of the potential and its distance from the
