  1. Seminar topic: “Monte-Carlo simulation of the OLVE-HERO Orbital Experiment”

    Speaker: Ilyas Satyshev

    Авторы: Ilyas Satyshev, Anatoly Pan, Khussein Karatash, Eldos Sholtan

    Abstract:

    The High Energy Ray Observatory (HERO) is a project for a space experiment based on an ionization calorimeter to measure the spectrum and composition of cosmic rays. The effective geometric factor of the installation is not less than 12 m2sr for protons and not less than 16 m2sr for nuclei and electrons. During 5-7 years of exposure, this mission will measure the element-by-element spectra of cosmic rays in the energy range 1012 -1016 eV/particle with high energy resolution. A Monte Carlo in the simulation toolkit GEANT4 of an experiment using a borated scintillator as part of a calorimeter is presented. The energy resolution, detector response and output signal magnitude were obtained.The planned experiment launch is no earlier than 2029.

  2. Seminar topic: “On computations of characteristics of qudits’ nonclassicality”

    Speaker: Astghik Torosyan

    Abstract:

    The results of the past three years of studying and determining the degree of classicality / quantumness of states of finite-dimensional quantum systems, which are based on a deviation of quasiprobability distributions from true statistical distributions, will be presented. In addition, a new parametrisation of the SU(4) group, which is well adapted to computational problems where the singular value decomposition is applicable, will be presented. The proposed representation will be used in further studies of the problem of entanglement of qudit states.
