  • Photoluminescence of ortho-bromobenzophenone 
    Avdeenko, A.A.; Pyshkin, O.S.; Eremenko, V.V.; Strzhemechny, M.A.; Buravtseva, L.M.; Romashkin, R.V. (Физика низких температур, 2006)
    Phosphorescence spectra of crystalline ortho-bromobenzophenone (2-bromobenzophenone, 2BrBP) were measured from 1.6 K to room temperature. A cardinal emission mechanism crossover occurs within this temperature range. At ...
  • Preface 
    Автор відсутній (Физика низких температур, 2006)
  • Present status of the theory of the high-Tc cuprates 
    Anderson, P.W. (Физика низких температур, 2006)
    The Gutzwiller projected mean-field theory, also called plain vanilla or renormalized meanfield theory, is explained and its successes and possible extensions in describing the phenomenology of the cuprate superconductors ...
  • Pseudogap and high-temperature superconductivity from weak to strong coupling. Towards quantitative theory (Review Article) 
    Tremblay, A.-M.S.; Kyung, B.; Sénéchal, D. (Физика низких температур, 2006)
    This is a short review of the theoretical work on the two-dimensional Hubbard model performed in Sherbrooke in the last few years. It is written on the occasion of the twentieth anniversary of the discovery of high-temperature ...
  • Pseudogaps: introducing the length scale into dynamical mean-field theory 
    Kuchinskii, E.Z.; Nekrasov, I.A.; Sadovskii, V.M. (Физика низких температур, 2006)
    Pseudogap physics in strongly correlated systems is essentially scale dependent. We generalize the dynamical mean-field theory (DMFT) by introducing into the DMFT equations dependence on the correlation length of ...
  • Rabi oscillations in systems with small anharmonicity 
    Amin, M.H.S. (Физика низких температур, 2006)
    When a two-level quantum system is irradiated with a microwave signal in resonance with the energy difference between the levels, it starts Rabi oscillations between those states. If there are other states close, in ...
  • Recent observation of anomalous superconducting behavior of ultrathin YBCO films and single crystals of cluster borides 
    Gasparov, V.A. (Физика низких температур, 2006)
    We report the number of deviations from conventional behavior in superconducting properties of ultrathin (1–3 unit-cell (UC)) YBa₀₂Cu₃O₇₋x films sandwiched between semiconducting Pr₀,₆Y₀,₄Ba₂Cu₃O₇₋x layers and for single ...
  • Resonant effects in the strongly driven phase-biased Cooper-pair box 
    Shevchenko, S.N.; Omelyanchouk, A.N. (Физика низких температур, 2006)
    We study the time-averaged upper level occupation probability in a strongly driven two-level system, particularly its dependence on the driving amplitude x₀ and frequency ω and the energy level separation ∆E. In contrast ...
  • Spectroscopy of atomic and molecular defects in solid ⁴He using optical, microwave, radio frequency, magnetic and electric fields (Review Article) 
    Moroshkin, P.; Hofer, A.; Ulzega, S.; Weis, A. (Физика низких температур, 2006)
    A little more than a decade ago our team extended the field of defect spectroscopy in cryocrystals to solid ⁴He matrices, in both their body-centered cubic (bcc) and hexagonally close-packed (hcp) configurations. In this ...
  • Spectroscopy of nanosized composites silicon-organic polymer/nanoporous silicas 
    Ostapenko, N.; Kozlova, N.; Suto, S.; Watanabe, A. (Физика низких температур, 2006)
    Fluorescence and excitation spectra (T = 5–290 K) of nanosized silicon–organic polymers poly(di-n-hexylsilane) and poly(methyl(phenyl)silane) incorporated into porous silica materials MCM-41 and SBA-15 have been studied ...
  • Spin dynamics in cuprate perovskites 
    Sherman, A.; Schreiber, M. (Физика низких температур, 2006)
    Results obtained with the use of the t–J model of Cu–O planes and Mori’s projection operator formalism are compared with data of neutron scattering experiments in lanthanum and yttrium cuprates. This comparison allows ...
  • Spin excitations in layered cuprates: a Fermi-liquid approach 
    Eremin, I.; Manske, D. (Физика низких температур, 2006)
    We review some important aspects of the doping dependence of many physical properties of the high-Tc cuprates based on a Fermi liquid-like approach. In particular, we show that the spin fluctuation-mechanism of ...
  • Stripe phases — possible ground state of the high-Tc superconductors 
    Raczkowski, M.; Oles, A.M.; Fresard, R. (Физика низких температур, 2006)
    Based on the mean-field method applied either to the extended single-band Hubbard model or to the single-band Peierls-Hubbard Hamiltonian we study the stability of both site-centered and bond-centered charge domain walls. ...
  • Superconducting gap and pseudogap 
    Guy Deutscher (Физика низких температур, 2006)
    The discovery of the pseudogap has been a fundamental advance in uncovering the new physics of the high-Tc cuprates. Yet, its meaning is still far from being clear. In particular, its relation to the superconducting gap ...
  • Superconductivity and antiferromagnetism in quasi-one-dimensional organic conductors (Review Article) 
    Dupuis, N.; Bourbonnais, C.; Nickel, J.C. (Физика низких температур, 2006)
    We review the current understanding of superconductivity in the quasi-one-dimensional organic conductors of the Bechgaard and Fabre salt families. We discuss the interplay between superconductivity, antiferromagnetism, ...
  • Temperature–carrier-concentration phase diagram of a two-dimensional doped d-wave superconductor 
    Loktev, V.M.; Turkowski, V.M. (Физика низких температур, 2006)
    The finite-temperature properties of a two-dimensional d-wave superconductor with the Lifshitz disorder, introduced by dopants, are studied. The doping dependence of the mean-field critical temperature Tc MF and of the ...
  • The distribution of field-induced charges in C₆₀ fullerite 
    Kuprievich, V.A.; Kapitanchuk, O.L.; Shramko, O.V.; Kudritska, Z.G. (Физика низких температур, 2006)
    The profile of injected charges in a C₆₀-based field-effect transistor (FET) is considered. A simple scheme for calculations of the charge distribution between the 2D layers of C₆₀ molecules is founded on a small magnitude ...
  • Theory of antiferromagnetic pairing in cuprate superconductors (Review article) 
    Plakida, N.M. (Физика низких температур, 2006)
    A review of the antiferromagnetic exchange and spin-fluctuation pairing theory in the cuprate superconductors is given. We briefly discuss a phenomenological approach and a theory in the limit of weak Coulomb correlations. ...
  • The physics of rotational tunneling: hole-burning spectroscopy of methyl groups 
    Somoza, M.M.; Friedrich, J. (Физика низких температур, 2006)
    Methyl groups are most outstanding quantum systems due to their inherent symmetry properties which cannot be destroyed by any kind of lattice disorder. We show how optical hole-burning techniques can be employed to measure ...
  • The polymerization of acetylene on supported metal clusters 
    Gilb, S.; Arenz, M.; Heiz, U. (Физика низких температур, 2006)
    The polymerization of acetylene was studied by thermal programmed reaction on model catalysts consisting of size-selected Ag, Rh, and Pd atoms and Pdn (1 ≤ n ≤ 30) clusters on well-characterized MgO(111) thin films. In ...
