Ballistic conductance of a quantum sphere. (English) Zbl 1045.81553

Summary: The conductance of a quantum sphere with two one-dimensional wires attached to it is investigated. An explicit form for the conductance as a function of the chemical potential is found from first principles. The form and positions of the resonance maxima on a plot of the conductance are studied.
