    The cosmological model with two phantom scalar fields with the special choice of field’s potential is considered. The obtained regular solution describes a bounce with a subsequent transition to the de Sitter stage of ...

    We consider a thick brane model using two interacting scalar fields in 7D and 8D gravity. Using a special choice of potential energy, we obtain numerically regular asymptotically flat vacuum solutions. The possibility ...

    A generalization of the phenomenological S-matrix model taking into account isolated Regge poles is proposed for simultaneously describing refractive effects in the cross sections for the elastic and inelastic scattering ...
  • Dzhunushaliev Vladimir (2012-06-30)
    We present thick de Sitter brane solutions which are supported by two interacting phantom scalar fields in five-, six- and seven-dimensional spacetime. It is shown that for all cases regular solutions with anti-de Sitter ...
  • Dzhunushaliev Vladimir (2012-06-30)
    The idea is considered that a quantum wormhole in a spacetime foam can be described as a Ricci flow. In this interpretation the Ricci flow is a statistical system and every metric in the Ricci flow is a microscopical ...
  • Dzhunushaliev Vladimir (2012-06-30)
    A model of Dark Matter is proposed where the Dark Matter is a classical color field. The color fields are invisible as they may interact with colored elementary particles like the ’t Hooft–Polyakov monopole only. Comparison ...
  • K.O.Sabdenov (2012-06-30)
    A physical explanation for the existence of the threshold of erosive burning is proposed. It is shown that this type of combustion occurs when the thickness of the laminar sublayer in the turbulent boundary layer becomes ...
  • V.Dzhunushaliev (2012-06-30)
    It is shown that the supersymmetric quantum mechanics has an octonionic generalization. The generalization is based on the inclusion of quaternions into octonions. The elements from the coset octonions/quaternions are ...
  • V. Dzhunushaliev (2012-06-30)
    A thick brane in six dimensions is constructed using two scalar fields. The field equations for 6D gravity plus the scalar fields are solved numerically. This thick brane solution shares some features with previously ...
  • Anco Stephen C; Myrzakulov R. (2012-06-30)
    A moving frame formulation of non-stretching geometric curve flows in Euclidean space is used to derive a 1+1 dimensional hierarchy of integrable SO(3)-invariant vector models containing the Heisenberg ferromagnetic spinmodel ...
  • Dzhunushaliev Vladimir;; Myrzakulov Kairat; Myrzakulov Ratbay (2012-06-30)
    The boson star filled with two interacting scalar fields is investigated. The scalar fields can be considered as a gauge condensate formed by SU(3) gauge field quantized in a non-perturbative manner. The corresponding ...
  • Dzhunushaliev Vladimir (2012-06-30)
    Toy models of a nonassociative quantum mechanics are presented. The Heisenberg equation of motion is modified using a nonassociative commutator. Possible physical applications of a nonassociative quantum mechanics are ...
  • Dzhunushaliev Vladimir; Folomeev Vladimir; Myrzakulov Kairat (2012-06-30)
    The model of cosmic string formed from two gravitating and interacting scalar fields is considered. It is shown that the regular solutions exist at special choice of the model’s parameters only.
  • Dzhunushaliev Vladimir; Folomeev Vladimir; Myrzakul Shynaray (2012-06-30)
    A model of a thick brane in 5D bulk supported by two phantom scalar fields is considered. The comparison with a thick brane supported by two usual scalar fields is carried out. The distinctions between a thick brane ...

    This work examines the generation of F2 centers in LiF, LiF〈O,OH〉, and LiF:U〈O,OH〉 crystals by electron pulses at 300 K. We discuss nanosecond and microsecond mechanisms for the excitation of pulsed cathodoluminescence ...

    The results of ab initio slab calculations of surface relaxations, rumplings and charge distribution for the different terminations of the MgF2 (011) and (111) polar surfaces are presented and discussed. We have employed ...

    We consider a configuration consisting of a wormhole filled by a perfect fluid. Such a model can be applied to describe stars as well as neutron stars with a nontrivial topology. The presence of a tunnel allows for motion ...

    A self-similar motion of the generalized Chaplygin gas in its own gravitational field is considered. The problem is studied numerically and analytically (in the limiting cases). It is shown that the model under consideration ...

    It is shown that the Hamilton equations in supersymmetric quantum mechanics can be presented in nonassociative form, where the Hamiltonian is decomposed into two nonassociative factors.
