  • FLAVOR OF SUPERSYMMETRY

    2015.04.17 14:56 - admin

    The most general flavor structure of the Minimal Supersymmetric Standard Model will be discussed. Experimental constraints on magnitudes of flavor-violating supersymmetric parameters, both in the squark and in the slepton sectors, will be reviewed. Finally, some examples on how MSSM non-trivial flavor structure can affect Higgs physics, Yukawa coupling unification, and direct SUSY searches at the LHC will be given.

  • Cosmological singularity problem

    2015.03.05 10:00 - admin

    Observational cosmology and known general relativity models of the Universe strongly suggest an existence of the initial cosmological singularity. The BKL scenario is thought to be a generic solution to the Einstein equations near the singularity. One believes that imposition of quantum rules onto this scenario may heal the singularity. Quantum BKL scenario could be used as a realistic model of the very early Universe. The Bianchi IX model underlies the BKL so its quantization should open the door to the quantization of the BKL. We present some preliminary analysis concerning this issue.

  • Nuclear fusion & fission and new sources of power

    2015.01.22 14:12 - admin

    Efficiency of nuclear reactors used by power industries all over the world already for several tens of years is not satisfactory as compared to other power sources. The new Dual Fluid Reactor concept worked out in Szczecin might bypass disadvantages of the currently used solutions. The method of comparing different power sources will be introduced. Capabilities of nuclear fusion technology based either on high-temperature plasma or on nuclear reactions occuring at extremely low energies takong advantage of the electron screening effect will be presented.

  • Supersymmetry on the eve of the LHC RUN II

    2015.01.12 8:29 - admin

    I will discuss the present status of supersymmetry after the null results of direct searches at the first run of the LHC. I will address issues of the naturalness of the theory and highlight a few misconceptions commonly found in the literature. I will argue that there is plenty of room for hope of a discovery in the 14 TeV run of the LHC, or in upcoming dark matter detection searches.

  • From quantum-mechanical models of bimolecular systems to causality analysis of structural changes

    2014.12.15 13:38 - MarcinSadowski

    Mechanisms of structural changes in (bio)molecular systems can either be determined from experimental probability distributions or from physics-based multiscale simulations, including microscopic theories, e.g. Molecular Mechanics/Molecular Dynamics (MM/MD), Quantum Dynamics (QD), Quantum-Classical Molecular Dynamics (QCMD), or mezoscopic models such as Lagrangian and Quaternion Molecular Dynamics (LQMD) or Brownian Dynamics (BD).  Symplectic algorithms conserving the total energy are preferable in molecular dynamics simulations.
