    Spectra of soft ring graphs

  • Original language description

    We discuss a ring-shaped soft quantum wire modelled by 6 interaction supported by the ring with a generally nonconstant coupling strength. We derive the condition which determines the discrete spectrum of such systems, and analyse the dependence of the eigenvalues and eigenfunctions on the coupling and ring geometry. In particular, we illustrate that a random component in the coupling leads to a localization. The discrete spectrum is also investigated in the situation when the ring is placed into a homogeneous magnetic field or threaded by an Aharonov-Bohm flux and the system exhibits persistent currents.

    Spektra měkkých prstencovýh grafů

  • Czech description

    Byl studován měkký kvantový drát prstencovitého tvaru modelovaný 6ti interakcemi nesenými prstencem, obecně s nekonstantní vazbou. Byly diskutovány spektrální vlastnosti v závislosti na vazbách. Byl vyšetřován také systém vložený v homogenním magnetickémpoli.
