  1. 55. Modeling short gamma ray bursts from binary neutron star mergers with general relativistic magnetohydrodynamics
    Prof. Agnieszka Janiuk (Center for Theoretical Physics PAS)
    24/09/2019, 12:30
    Selected Talks
    Talk/Seminar

    I will present the recent development of numerical tools for GR MHD modeling of the black hole accretion flows.
    The black hole appears as the result of a binary neutron star merger, and is surrounded by a remnant debris torus.
    The code named HARM_COOL is our implementation of the existing algorithm
    for a conservative GR MHD scheme.
    The newly added modules cover the neutino cooling and the...

  2. 21. Canonical Quantization of Massive Symmetric Rank-Two Tensor in String Theory
    Prof. Taejin Lee (Department of Physics, Kangwon National University)

    Selected Talks
    Talk/Seminar

    Canonical quantization of massive symmetric rank-two tensor in string theory has been studied.
    The Lagrangian describing symmetric rank-two tensor, containing two Stueckelberg fields,
    was obtained by Siegel and Zwiebach from string field theory. Performing canonical analysis,
    we found that the Lagrangian possesses first class constraints only, which generate a local gauge transformation....

  3. 65. On the precanonical structure of the Schroedinger wave functional in curved space-time
    Dr Igor Kanatchikov (U St. Andrews & KCIK)

    Selected Talks
    Talk/Seminar

    I outline the approach of precanonical quantization applied to a scalar field on curved space-time. It leads to the description of quantum fields as sections of the Clifford bundle over the bundle of field variables over space-time. The approach does not require 3+1 decomposition and the corresponding description of quantum fields is a hypercomplex rather than an infinite-dimensional...

  4. 84. Searching for non-Riemannian signatures in cosmological data
    Dr Krzysztof Bolejko (University of Tasmania)
    26/09/2019, 14:00
    Selected Talks
    Talk/Seminar

    The Einstein's theory of gravity, General Relativity was build on the theory of Special Relativity. This generalisation required utilising the full generality of the Riemannian geometry. Many of the present-day cosmological tests of GR are still based on the assumption of the Riemannian geometry. However, in order to fully study and test various extensions of GR one is also required to move...

  5. 47. Quantum creation of a universe-antiuniverse pair
    Salvador Robles-Perez (EEBM)
    26/09/2019, 14:40
    Selected Talks
    Talk/Seminar

    If one analyses the quantum creation of the universe, it turns out that the most natural way in which the universes can be created is in pairs of universes whose time flow is reversely related. It means that the matter that propagates in one of the universes can be seen, from the point of view of the other universe, as antimatter, and viceversa. They thus form a universe-antiuniverse pair....
