    Comment on “Path to collapse for an isolated Néel skyrmion” 
    Bessarab, Pavel (American Physical Society (APS), 2017-04-24)
    Rohart et al. [Phys. Rev. B 93, 214412 (2016)] recently reported calculations indicating two mechanisms for the annihilation of a skyrmion in a Co monolayer on Pt(111). The path calculations were based on a method presented in the Supplemental Material ...

    Energy surface and lifetime of magnetic skyrmions 
    Uzdin, V.M.; Potkina, M.N.; Lobanov, I.S.; Bessarab, Pavel; Jónsson, Hannes (Elsevier BV, 2017-11)
    The stability of skyrmions in various environments is estimated by analyzing the multidimensional surface describing the energy of the system as a function of the directions of the magnetic moments in the system. The energy is given by a Heisenberg-like ...

    Stability and lifetime of antiferromagnetic skyrmions 
    Bessarab, Pavel; Yudin, D.; Gulevich, D. R.; Wadley, P.; Titov, M.; Tretiakov, Oleg A. (American Physical Society (APS), 2019-04-26)
    The two-dimensional Heisenberg exchange model with out-of-plane anisotropy and a Dzyaloshinskii-Moriya interaction is employed to investigate the lifetime and stability of antiferromagnetic (AFM) skyrmion as a function of temperature and external ...

    Thermal generation of droplet soliton in chiral magnet 
    Kuchkin, Vladyslav; Bessarab, Pavel; Kiselev, Nikolai S. (American Physical Society (APS), 2022-05-02)
    Controlled creation of localized magnetic textures beyond conventional π-skyrmions is an important problem in the field of magnetism. Here, by means of spin dynamics simulations, Monte Carlo simulations, and harmonic transition state theory we demonstrate ...
