  • On dissociation in weakly doped ice 
    Chikina, I.; Shikin, V. (Физика низких температур, 2015)
    Currently, there is some ambiguity in the problem of decay of a single donor into charged fragments. Thus, in the well-known Ostwald approximation used for semiconductors (ice being one of them) the donor dissociation degree ...
  • On the limits of application of Anderson and Kondo models in physics of strongly correlated electron systems 
    Sluchanko, N.E. (Физика низких температур, 2015)
    We argue that the Anderson and Kondo models turn out to be irrelevant for the description of some strongly correlated electron systems and suggest the mechanism for the formation of many-body states (heavy fermions) being ...
  • Optical spectroscopy and current detection during warm-up and destruction of impurity–helium condensates 
    Krushinskaya, I.N.; Boltnev, R.E.; Bykhalo, I.B.; Pelmenev, A.A.; Khmelenko, V.V.; Lee, D.M. (Физика низких температур, 2015)
    New experimental results on detection of optical spectra and ion currents during destruction of impurity–helium condensates (IHCs) have been obtained. It is shown that emission during IHC sample destruction is accompanied ...
  • Phase diagram of the polymeric nitrogen 
    Yakub, L.N. (Физика низких температур, 2015)
    The results of theoretical prediction of the phase transition lines of molecular nitrogen into the polymeric phase at high pressure are presented. The role of the polymeric phase structure in the location of the ...

    Manzhelii, E.V.; Feodosyev, S.B.; Gospodarev, I.A.; Syrkin, E.S.; Minakova, K.A. (Физика низких температур, 2015)
    The atomic dynamics of linear chains embedded in a crystalline matrix or adsorbed on its surface is studied. A linear chain formed by substitutional impurities in a surface layer and at the same time offsetting from ...
  • Physical modeling of the formation of clathrate hydrates of methane 
    Drobyshev, A.; Aldiyarov, A.; Kurnosov, V.; Katpaeva, K.; Korshikov, E.; Sokolov, D.; Shinbayeva, A.; Timchenko, A. (Физика низких температур, 2015)
    Nowadays natural gas hydrates attract special attention as a possible source of fossil fuel. According to various estimates, the reserves of hydrocarbons in hydrates exceed considerably explored reserves of natural gas. Due ...
  • Poisson’s ratio in cryocrystals under pressure 
    Freiman, Yu.A.; Grechnev, A.; Tretyak, S.M.; Goncharov, Alexander F.; Gregoryanz, Eugene (Физика низких температур, 2015)
    We present results of lattice dynamics calculations of Poisson’s ratio (PR) for solid hydrogen and rare gas solids (He, Ne, Ar, Kr and Xe) under pressure. Using two complementary approaches — the semi-empirical many-body ...
  • Preface 
    Strzhemechny, M.A. (Физика низких температур, 2015)
  • Propagation of acoustic edge waves in graphene under quantum Hall effect 
    Vikström, A. (Физика низких температур, 2015)
    We consider a graphene sheet with a zigzag edge subject to a perpendicular magnetic field and investigate the propagation of in-plane acoustic edge waves. In particular it is shown that propagation is significantly blocked ...
  • Pseudogap from ARPES experiment: three gaps in cuprates and topological superconductivity (Review Article) 
    Kordyuk, A.A. (Физика низких температур, 2015)
    A term first coined by Mott back in 1968 a “pseudogap” is the depletion of the electronic density of states at the Fermi level, and pseudogaps have been observed in many systems. However, since the discovery of the ...
  • Scattering of high-energy magnons off a magnetic skyrmion 
    Schroeter, S.; Garst, M. (Физика низких температур, 2015)
    We discuss the scattering of high-energy magnons off a single magnetic skyrmion within the field-polarized ground state of a two-dimensional chiral magnet. For wavevectors larger than the inverse skyrmion radius,krs>>1 ...
  • Shielding characteristics of water 
    Levchenko, A.A.; Likhter, A.M.; Khramov, D.A.; Gryaznova, V.A.; Shikin, V.B. (Физика низких температур, 2015)
    In this article we demonstrate that a relatively small density of intrinsic ions in pure water has a significant impact on the development of the instability of the liquid–vapor boundary in an external electric field ...
  • Spin Nernst effect and intrinsic magnetization in two-dimensional Dirac materials 
    Gusynin, V.P.; Sharapov, S.G.; Varlamov, A.A. (Физика низких температур, 2015)
    We begin with a brief description of the role of the Nernst–Ettingshausen effect in the studies of the hightemperature superconductors and Dirac materials such as graphene. The theoretical analysis of the NE effect is ...
  • Spin waves damping in nanometre-scale magnetic materials 
    Krivoruchko, V.N. (Физика низких температур, 2015)
    Spin dynamics in magnetic nanostructured materials is a topic of great current interest. To describe spin motions in such magnetic systems, the phenomenological Landau–Lifshitz (LL), or the LL–Gilbert (LLG), equation is ...
  • Structural and phase transitions in nanocluster ethanol samples at low temperatures 
    Efimov, V.; Izotov, A.; Mezhov-Deglin, L.; Nesvizhevskii, V.; Rybchenko, O.; Zimin, A. (Физика низких температур, 2015)
    Results of neutron (SANS study) and x-ray diffraction experiments with nanocluster samples of deuteroethanol (C₂D₅OD) or ordinary pure ethanol (C₂H₅OH) are presented. A deuterated ethanol sample, formed via quick cooling ...

    Monarkha, Yu.P. (Физика низких температур, 2015)
    The energy balance of strongly interacting surface electrons on liquid helium under cyclotron-resonance excitation is theoretically studied. The Coulomb interaction is shown to induce temperature bistability of the ...

    Nieves, P.; Atxitia, U.; Chantrell, R.W.; Chubykalo-Fesenko, O. (Физика низких температур, 2015)
    Micromagnetic modeling has proved itself as a widely used tool, complimentary in many respects to experimental measurements. The Landau–Lifshitz equation provides a basis for this modeling, especially where the dynamical ...

    Ellis, M.O.A.; Evans, R.F.L.; Ostler, T.A.; Barker, J.; Atxitia, U.; Chubykalo-Fesenko, O.; Chantrell, R.W. (Физика низких температур, 2015)
    The Landau–Lifshitz (LL) equation, originally proposed at the macrospin level, is increasingly used in Atomistic Spin Dynamic (ASD) models. These models are based on a spin Hamiltonian featuring atomic spins of fixed ...
