    Duplication, Collapse, and Escape of Magnetic Skyrmions Revealed Using a Systematic Saddle Point Search Method 
    Müller, Gideon Philipp; Bessarab, Pavel; Vlasov, Sergei M.; Lux, Fabian; Kiselev, Nikolai S.; Blügel, Stefan; Uzdin, Valery M.; Jónsson, Hannes (American Physical Society (APS), 2018-11-06)
    Various transitions that a magnetic Skyrmion can undergo are found in calculations using a method for climbing up the energy surface and converging onto first order saddle points. In addition to collapse and escape through a boundary, the method ...

    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 ...

    Quantum mechanical tunneling between magnetic states 
    Vlasov, Sergei M. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-12)
    Nanomagnetic systems and transitions between magnetic states are currently an active topic of research. Spintronics is, in particular, a new branch of science and technology where spin degrees of freedom and spin currents are used in an analogous way ...
