    Vibrations of thick domain walls: How to avoid no-go theorem
    (2020) Gani, V. A.; Гани, Вахид Абдулович
    © Published under licence by IOP Publishing Ltd.The asymptotic properties of the stability potentials of kinks with power-law tails are discussed. In particular, in cosmology such kinks can describe "thick"domain walls. The discrete part of the domain wall excitation spectrum, the profile of which is described by a kink solution with one or both power-law asymptotics, cannot contain levels other than zero (translational) mode. Nevertheless, it can be shown that scenarios are quite possible when long-lived localized vibrations will be excited on the domain wall. This, in turn, can affect the processes of interaction of two or more domain walls.

    Equilibration of sinusoidal modulation of temperature in linear and nonlinear chains
    (2020) Korznikova, E. A.; Kuzkin, V. A.; Krivtsov, A. M.; Xiong, D.; Gani, V. A.; Гани, Вахид Абдулович
    © 2020 American Physical Society.The equilibration of sinusoidally modulated distribution of the kinetic temperature is analyzed in the β-Fermi-Pasta-Ulam-Tsingou chain with different degrees of nonlinearity and for different wavelengths of temperature modulation. Two different types of initial conditions are used to show that either one gives the same result as the number of realizations increases and that the initial conditions that are closer to the state of thermal equilibrium give faster convergence. The kinetics of temperature equilibration is monitored and compared to the analytical solution available for the linear chain in the continuum limit. The transition from ballistic to diffusive thermal conductivity with an increase in the degree of anharmonicity is shown. In the ballistic case, the energy equilibration has an oscillatory character with an amplitude decreasing in time, and in the diffusive case, it is monotonous in time. For smaller wavelength of temperature modulation, the oscillatory character of temperature equilibration remains for a larger degree of anharmonicity. For a given wavelength of temperature modulation, there is such a value of the anharmonicity parameter at which the temperature equilibration occurs most rapidly.

    Kink-Kink and Kink-Antikink Interactions with Long-Range Tails
    (2019) Christov, Ivan C.; Decker, Robert J.; Demirkaya, A.; Kevrekidis, P. G.; Gani, Vakhid A.; Гани, Вахид Абдулович
    In this Letter, we address the long-range interaction between kinks and antikinks, as well as kinks and kinks, in phi(2n+4) field theories for n > 1. The kink-antikink interaction is generically attractive, while the kink-kink interaction is generically repulsive. We find that the force of interaction decays with the 2n/(n - 1)th power of their separation, and we identify the general prefactor for arbitrary n. Importantly, we test the resulting mathematical prediction with detailed numerical simulations of the dynamic field equation, and obtain good agreement between theory and numerics for the cases of n = 2 (phi(8) model), n = 3 (phi(10) model), and n = 4 (phi(12) model).

    Exotic final states in the φ8 multi-kink collisions
    (2021) Moradi, Marjaneh, A.; Javidan, K.; Gani, V. A.; Гани, Вахид Абдулович
    © 2021, The Author(s).We study final states in the scattering of kinks and antikinks of the φ8 field-theoretic model. We use the initial conditions in the form of two, three or four static or moving kinks. In the numerical experiments we observe a number of different processes such as emergence of static and moving oscillons, change of the kink’s topological sector, scattering of an oscillon by a kink, production of kink–antikink pairs in oscillon–oscillon collisions. In antikink–kink collisions for asymmetric kinks, we found resonance phenomena – escape windows.

    Kinks in higher-order polynomial models
    (2022) Blinov, P. A.; Gani, T. V.; Malnev, A. A.; Gani, V. A.; Sherstyukov, V. B.; Гани, Вахид Абдулович
    We consider a family of field-theoretic models with a real scalar field in (1+1)-dimensional space-time. The field dynamics in each model is determined by a polynomial potential with two degenerate minima. We obtain exact general formulas for kink solutions with power-law asymptotic behavior. We also write out formulas for the asymptotics of all found kinks. In addition, we analyze some other properties of the obtained kinks: stability potentials, zero modes, positions of the centers of mass.

    Remarks on sine-Gordon kink–fermion system: localized modes and scattering
    (2022) Gani, V. A.; Gorina, A.; Perapechka, I.; Shnir, Y.; Гани, Вахид Абдулович
    We study numerically the kink–fermion interactions in a 1 + 1 dimensional toy model, which describes sine-Gordon kinks coupled to the massless Dirac fermions with backreaction. We show that the spectrum of fermionic modes strongly depends on the choice of the coupling, in particular, there are no localized modes for a minimal Yukawa coupling. We analyze the scattering of the fermionic packet by the kink. We demonstrate that the outcome of the collision dynamically depends on the phase of the incoming fermion packet, it results in alternating regimes of positive and negative acceleration of the kink. © 2022, The Author(s).

    Deformations of kink tails
    (2022) Blinov, P. A.; Gani, T. V.; Gani, V. A.; Гани, Вахид Абдулович
    © 2021 Elsevier Inc.We study the asymptotic properties of kinks in connection with the deformation procedure. We show that, upon deformation of the field-theoretic model, the asymptotics of kinks can change or remain unchanged, depending on the properties of the deforming function. The cases of both explicit and implicit kinks are considered. In addition, we show that the deformation procedure can be applied to the important case of implicit kinks. We also prove that for any kink with a power-law tail, the stability potential decreases as the inverse square of the coordinate. The physical consequences of the deformation are discussed: the change of the kink mass, as well as the asymptotic behavior of the kink–antikink force.
