  • Do tunneling states and boson peak persist or disappear in extremely stabilized glasses? 
    Ramos, M.A.; Pérez-Castañeda, T.; Jiménez-Riobóo, R.J.; Rodríguez-Tinoco, C.; Rodríguez-Viejo, J. (Физика низких температур, 2015)
    We review and concurrently discuss two recent works conducted by us, which apparently give opposite results. Specifically, we have investigated how extreme thermal histories in glasses can affect their universal properties ...

    The experimental setup for obtaining and determination of the thermal conductivity of simple van der Waals crystal-based nanocomposites is described. Preliminary thermal conductivity results of measurements carried out in ...
  • Low-temperature thermodynamics of Xe-doped fullerite C₆₀ 
    Klochko, M.S.; Strzhemechny, M.A. (Физика низких температур, 2015)
    Using a model of the fullerene C₆₀ molecule with carbon atoms uniformly distributed over its surface, the potential energy U(n) of a Xe atom in an octahedral void of C₆₀ is calculated. Within the framework of threedimen ...
  • Mechanisms of self-screening in pure ice 
    Chikina, I.; Shikin, V. (Физика низких температур, 2015)
    Possible approaches to a correct account of the Coulomb interaction in system of proton-hydroxyl pairs in pure ice (a proton version of intrinsic semiconductor) are discussed for a possibility to evaluate correlation ...
  • Melting of cryocrystals at high pressures. Computer simulation 
    Yakub, E.S. (Физика низких температур, 2015)
    Simple molecular models were applied to predict melting temperature of highly compressed classical molecular crystals of hydrogen and nitrogen in a wide range of pressures and temperatures using conventional molecular dynamics ...
  • Molecular dynamics simulation of thermodynamic and transport properties of H-bonded low-temperature substances 
    Tychengulova, A.; Aldiyarov, A.; Drobyshev, A. (Физика низких температур, 2015)
    The results of modeling of isotopic water mixture clusters in nitrogen and argon cryomatrices are presented. Earlier, our experimental studies of water mixture in cryomatrix have shown that changes in the concentration ...
  • 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 ...
  • 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 ...

    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 ...
