The process of the fluxon assisted qubit readout in the Josephson transmission line has been investigated in detail. The dependence of the threshold pinning current for the fluxon has been obtained as a function of the discreteness parameter, impurity strength and the dissipation constant. It was shown how the fluxon delay time depends on the impurity strength and the dissipation constant. The studies of the linear excitations in the Josephson arrays has been continued. The influence of the spatial inhomogeneities on the plasmon properties in the Josephson transmission lines has been studied, the localized mode frequency that appears due to the impurity junction with different critical current and different external bias has been computed. The article is published in the journal Physica E (Q2) that contains the following result: The three-dimensional Poisson equation for the potential created by two coaxial metal contacts at the edges of the Corbino disk is analytically solved. It is assumed that there is a finite tangential current, while the radial current is absent. This solution is compared to the solution of the two-dimensional problem for the conducting Corbino disk. The obtained results are used as a physical justification of how it is possible to create practically an electric potential in Corbino geometry, in which we study the collapse of Landau levels. The study of the collapse of Landau levels in Dirac materials, in particular, in a radial electric field is continued.
