  • Josephson effect in a weak link between borocarbides 
    Kolesnichenko, Yu.A.; Shevchenko, S.N. (Физика низких температур, 2005)
    A stationary Josephson effect is analyzed theoretically for a weak link between borocarbide superconductors. It is shown that different models of the order parameter result in qualitatively different current-phase relations.

    Level statistics for two classes of disordered systems at criticality are analyzed in terms of different realizations of the Chalker–Coddington network model. These include: 1) Re-examination of the standard U(1) model ...
  • Localized-magnon states in strongly frustrated quantum spin lattices 
    Richter, J. (Физика низких температур, 2005)
    Recent developments concerning localized-magnon eigenstates in strongly frustrated spin lattices and their effect on the low-temperature physics of these systems in high magnetic fields are reviewed. After illustrating ...

    Kadigrobov, A.; Shekhter, R.I.; Jonson, M. (Физика низких температур, 2005)
    A new principle for a compact spin-based solid-state laser is proposed. It operates in the 1–100 THz regime, which is difficult to reach with small size lasers. Spin-flip processes in ferromagnetic conductors form a basis ...
  • One-dimensional electron lattice system with a long-range interelectron repulsion on a disordered host lattice 
    Slutskin, A.A.; Kovtun, H.A. (Физика низких температур, 2005)
    We study what happens to generalized Wigner crystal, GWC (a regular structure formed by narrow-band electrons on a one-dimensional periodic host lattice), when there is a host lattice random distortion that does not break ...

    Gogadze, G.A. (Физика низких температур, 2005)
    Theory of the reentrant effect in susceptibility of mesoscopic cylindrical NS samples is proposed, which is essentially based on the properties of the Andreev levels. The specific feature of the quantum levels of the ...
  • On the polyamorphism of fullerite-based orientational glasses 
    Aleksandrovskii, A.N.; Bakai, A.S.; Cassidy, D.; Dolbin, A.V.; Esel’son, V.B.; Gadd, G.E.; Gavrilko, V.G.; Manzhelii, V.G.; Moricca, S.; Sundqvist, B. (Физика низких температур, 2005)
    The dilatometric investigation in the temperature range of 2–28 K shows that a first-order polyamorphous transition occurs in the orientational glasses based on C₆₀ doped with H₂, D₂ and Xe. A polyamorphous transition ...
  • Ordering in two-dimensional Ising models with competing interactions 
    Chitov, G.Y.; Gros, C. (Физика низких температур, 2005)
    We study the 2D Ising model on a square lattice with additional non-equal diagonal next-nearest neighbor interactions. The cases of classical and quantum (transverse) models are considered. Possible phases and their ...
  • Paramagnetic effect of the magnetic field on superconductors with charge-density waves 
    Ekino, T.; Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2005)
    The limiting field Hp for spin-singlet superconductors with charge-density waves (CDWs), which paramagnetically destroys the ordered phase, possessing coexisting superconducting and CDW order parameters, is calculated ...

    Electronic correlation effects in La₂-xSrxNiO₄ (x = 1/3 and 0.225) lead to spontaneous phase separation into microscopic spin/charge stripes with commensurate and incommensurate order, respectively. Raman scattering ...
