Extraction of Inductances and Spatial Distributions of Currents in a Model of Superconducting Neuron
Publikováno v:
Computational Mathematics and Mathematical Physics. 61:854-863
A mathematical model and a computational method for extracting the inductances and spatial distributions of supercurrents in an adiabatic artificial neuron are proposed. This neuron is a multilayer structure containing Josephson junctions. The comput

We consider the problem of mathematical modeling of the current distribution in Josephson structures based on semiclassical equations of the microscopic theory of superconductivity (the Usadel equations). These equations are a system of quasilinear e

In this work, we investigate two-dimensional arrays of High-T C superconducting quantum interference devices (SQUIDs) for optimization of their electrical transport characteristics. Specifically, we look at devices with different electrode configurat

For optimal control problems, a new approach based on the search for an extremum of a special functional is proposed. The differential problem is reformulated as an ill-posed variational inverse problem. Taking into account ill-posedness leads to a s

A functional-based variational method is proposed for finding the eigenfunctions and eigenvalues in the Sturm–Liouville problem with Dirichlet boundary conditions at the left endpoint and Neumann conditions at the right endpoint. Computations are p

Trapping of residual magnetic field degrades the performance and, in extreme cases, destroys operability of superconductor digital circuits. It is known that moats or narrow cuts made in superconductor thin films are able to “immunize” them from

We study the spatial distribution of supercurrent circulated around an Abrikosov vortex in an SF bilayer in perpendicular magnetic field. Within the dirty limit regime and circular cell approximation for the vortex lattice, we derive the conditions w

Interest in the inverse Sturm–Liouville problem is motivated by its numerous applications in mathematics and computational physics. To solve a complete inverse problem, one needs two exact spectra, which are usually not known in experimental spectr

Vortices in quantum condensates exist owing to a macroscopic phase coherence. Here we show, both experimentally and theoretically, that a quantum vortex with a well-defined core can exist in a rather thick normal metal, proximized with a superconduct
