  • Abrikosov and the path to understanding high-Tc superconductivity 
    Juan Carlos Campuzano (Физика низких температур, 2018)
    An early attempt to try to understand the high superconducting transition temperatures in the cuprate super-conductors was Abrikosov's theory of extended Van Hove singularities. It was based on our early experimental data ...
  • Alexei Alexeevich Abrikosov (1928–2017) To the 90th birthday of A.A. Abrikosov 
    Varlamov, A.; Loktev, V. (Физика низких температур, 2018)
  • Amplitude-dependent internal friction in AZ31 alloy sheets submitted to accumulative roll bonding

    We study dynamical processes in coherently coupled atomic Bose–Einstein condensates. Josephson effects in ring-shaped and dumbbell geometries are theoretically investigated. Conditions for observation of the Josephson effect ...
  • Anatomy of point-contact Andreev reflection spectroscopy from the experimental point of view 
    Naidyuk, Yu.G.; Gloos, K. (Физика низких температур, 2018)
    We review applications of point-contact Andreev-reflection spectroscopy to study elemental superconductors, where theoretical conditions for the smallness of the point-contact size with respect to the characteristic lengths ...
  • Anomalous transport properties of Dirac and Weyl semimetals 
    Gorbar, E.V.; Miransky, V.A.; Shovkovy, I.A.; Sukhachov, P.O. (Физика низких температур, 2018)
    In this review we discuss a wide range of topological properties of electron quasiparticles in Dirac and Weyl semimetals. Their nontrivial topology is quantified by a monopole-like Berry curvature in the vicinity of Weyl ...
  • Berry phase in strained InSb whiskers 
    Druzhinin, A.; Ostrovskii, I.; Khoverko, Yu.; Liakh-Kaguy, N.; Rogacki, K. (Физика низких температур, 2018)
    Strain influence on the longitudinal magnetoresistance for the n-type conductivity InSb whiskers doped by Sn to concentrations 6·10¹⁶–6·10¹⁷ сm⁻³ were studied at temperatures from 4.2 to 50 K and magnetic field up to 10 ...
  • Bullets and droplets: Two-dimensional spin-wave solitons in modern magnonics 
    Sulymenko, O.R.; Prokopenko, O.V.; Tyberkevych, V.S.; Slavin, A.N.; Serga, A.A. (Физика низких температур, 2018)
    In this review we consider theoretical and experimental results related to the properties of two-dimensional spin-wave (SW) solitons, so-called SW bullets and SW droplets. Such nonlinear self-localized SW modes possess ...
  • Can high-Tc superconductivity in cuprates be explained by the conventional BCS theory? 
    Božović, I.; Bollinger, A.T.; Wu, J.; He, X. (Физика низких температур, 2018)
    For overdoped cuprates, it is believed that the normal state behaves as an ordinary Fermi liquid while the superconducting state conforms to the BCS theory. We have put these beliefs to the test by a comprehensive experiment ...
  • Channel electron bubbles in low-temperature helium gas 
    Monarkha, Yu.P. (Физика низких температур, 2018)
    Self-localization of electrons caused by their interaction with helium vapor atoms in quasi-one-dimensional conducting channels over liquid helium is theoretically studied. We have shown that channel electron bubbles of a ...
  • Compact discrete breathers on flat-band networks 
    Danieli, C.; Maluckov, A.; Flach, S. (Физика низких температур, 2018)
    Linear wave equations on flat-band networks host compact localized eigenstates (CLS). Nonlinear wave equations on translationally invariant flat-band networks can host compact discrete breathers-time-periodic and spatially ...
  • Convective heat transport in two-phase superfluid/vapor ⁴He system 
    Urban, P.; Hanzelka, P.; Vlček, I.; Schmoranzer, D.; Skrbek, L. (Физика низких температур, 2018)
    We have recently shown that under certain cryogenic conditions heat can flow from a colder but constantly heated body to a hotter but constantly cooled body. Specifically, we have provided experimental evidence that heat ...
  • Conventional and unconventional impurity effects in superconductors 
    Pogorelov, Yu.G.; Loktev, V.M. (Физика низких температур, 2018)
    A survey is done on the effects of impurities in different types of superconductors, both conventional and unconventional, on their electronic spectra and physical properties. These effects can be generally divided on the ...

    Kulinich, S.I.; Gorelik, L.Y. (Физика низких температур, 2018)
    We theoretically consider a nanomechanical link between two metallic leads subject to a temperature drop. It is shown that mechanical dynamics of such system can be strongly affected by a heat flow through it via the ...
