    Effect of anisotropy distribution on local nucleation field in bistable ferromagnetic microwires 
    Kwiatkowski, Grzegorz (AIP Publishing, 2019-06-07)
    Critical parameters defining the local nucleation field in amorphous ferromagnetic microwires with positive magnetostriction are obtained analytically through scaling procedures. An exact value of the nucleation field is obtained numerically as a ...

    Optimal Control of Magnetization Reversal in a Monodomain Particle by Means of Applied Magnetic Field 
    Kwiatkowski, Grzegorz J.; Badarneh, Mohammad H. A.; Berkov, Dmitry V.; Bessarab, Pavel (American Physical Society (APS), 2021-04-29)
    A complete analytical solution to the optimal reversal of a macrospin with easy-axis anisotropy is presented. An optimal control path minimizing the energy cost of the reversal is identified and used to derive the time-dependent direction and amplitude ...

    Optimal protocol for spin-orbit torque switching of a perpendicular nanomagnet 
    Vlasov, Sergei M.; Kwiatkowski, Grzegorz J.; Lobanov, Igor S.; Uzdin, Valery M.; Bessarab, Pavel (American Physical Society (APS), 2022-04-07)
    It is demonstrated by means of the optimal control theory that the energy cost of the spin-orbit torque induced reversal of a nanomagnet with perpendicular anisotropy can be strongly reduced by proper shaping of both in-plane components of the current ...

    Out-of-equilibrium hydrodynamics with and without boost symmetry 
    Rajagopal, Aruna (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021-05)
    In this thesis, we explore the role of symmetries in hydrodynamics by studying certain properties of relativistic and non-relativistic fluids. In the first part of the thesis, we examine the theory of relativistic magnetohydrodynamics (Maxwell ...
