   Numerical study of superconducting processes in Josephson structure models

   Abstract:
   

   The methods, software packages and results of numerical studies of physical processes occurring under the influence of various factors in the following models of Josephson structures are presented:

   • a model of a stack of long Josephson junctions (JJ) with the capacitive and inductive coupling between adjacent JJs
   • a model of a point anomalous ϕ0-junction with the spin-orbit and ferromagnetic coupling
   Numerical studies are characterized by a significant amount of calculations and require the use of parallel computing methods and technologies to organize high-performance computer modeling.

   Using the qbsolv and dwave-neal libraries for solving large quadratic unconstrained binary optimization problems in particle tracking algorithms

   Abstract:

   We compare the performance of two libraries, qbsolv and dwave-neal for solving large quadratic unconstrained binary optimization (QUBO) problems in the context of particle tracking. The study was done using the resources of the “HybriLIT” platform and uses TrackML data and an implementation of a tracking algorithm based on triplets, rather than doublets, as the main building block in the QUBO objective function.
