  1. Seminar topic: “Numerical study of superconducting processes in Josephson structure models”

    Speaker: Maxim Bashashin

    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.

    1. a model of a stack of long Josephson junctions (JJ) with the capacitive and inductive coupling between adjacent JJs;
    2. 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.


  2. Seminar topic: “Using the qbsolv and dwave-neal libraries for solving large quadratic unconstrained binary optimisation problems in particle tracking algorithms”

    Speaker: Martin Bures

    Abstract:

    The speaker compares the performance of two libraries, qbsolv and dwave-neal for solving large quadratic unconstrained binary optimisation (QUBO) problems in particle tracking. The study was done using the resources of the HybriLIT Platform, TrackML data, and a tracking algorithm based on triplets rather than doublets as the main building block in the QUBO objective function.
