  • Preface 
    Автор відсутній (Физика низких температур, 2007)
    This issue of Fizika Nizkikh Temperatur contains the selected plenary talks presented on the International Conference «Statistical Physics 2006. Condensed Matter: Theory and Applications (CMPT06)», 12–15 September, 2006, ...
  • Interlayer tunneling and the problem of superfluidity in bilayer quantum Hall systems 
    Fil, D.V.; Shevchenko, S.I. (Физика низких температур, 2007)
    A possibility of nondissipative transmission of electrical current from the source to the load using superfluid electron-hole pairs in bilayers is studied. The problem is considered with reference to quantum Hall bilayers ...
  • Effective conformational search methods for biological macromolecules 
    Çelik, T. (Физика низких температур, 2007)
    The configuration space of many complex physical systems presents a rough energy landscape consisting of tremendous number of local minima separated by high energy barriers. One way to overcome these barriers is to perform ...
  • Quantum bits with Josephson junctions (Review Article) 
    Wendin, G.; Shumeiko, V.S. (Физика низких температур, 2007)
    Recent demonstrations of macroscopic quantum coherence in Josephson junction based electronic circuits opened entirely new dimension for the research and applications in the established field of Josephson electronics. ...
  • Universal properties of highly frustrated quantum magnets in strong magnetic fields 
    Derzhko, O.; Richter, J.; Honecker, A.; Schmidt, H.-J. (Физика низких температур, 2007)
    The purpose of the present paper is two-fold. On the one hand, we review some recent studies on the low-temperature strong-field thermodynamic properties of frustrated quantum spin antiferromagnets which admit the so-called ...
  • Giant super-poissonian shot noise in spin-polarized SET structures 
    Gorelik, L.Y.; Kulinich, S.I.; Shekhter, R.I.; Jonson, M.; Vinokur, V.M. (Физика низких температур, 2007)
    We study transport of spin-polarized electrons through a magnetic single-electron transistor (SET) in the presence of an external magnetic field. Assuming the SET to have a nanometer-sized central island with a single ...
  • Impurity induced Dirac point smearing in graphene 
    Skrypnyk, Yu.V.; Loktev, V.M. (Физика низких температур, 2007)
    It is shown that in a two-dimensional system with the linear dispersion a resonance is present in the Dirac point vicinity, when the impurity perturbation magnitude exceeds the bandwidth. The corresponding spectrum rea ...
  • The unusual properties of anisotropic systems of quasiparticles in superfluid ⁴He 
    Adamenko, I.N.; Nemchenko, K.E.; Slipko, V.A.; Wyatt, A.F.G. (Физика низких температур, 2007)
    We discuss a number of unusual phenomena, which have been discovered recently in anisotropic quasiparticle systems in superfluid ⁴He. These include the creation of high-energy phonons by a pulse of low-energy phonons, ...
  • Charged snowball in nonpolar liquid 
    Chikina, I.; Shikin, V.; Varlamov, A. (Физика низких температур, 2007)
    The problem of correct definition of the charge carrier effective mass in superfluid helium is revised. It is demonstrated that the effective mass M of a such quasiparticle can be introduced without use of the Atkins’s idea ...
  • Spin modes in electron Fermi liquid of organic conductors 
    Peschansky, V.G.; Stepanenko, D.I. (Физика низких температур, 2007)
    The propagation of spin waves in Q2D layered conductors placed in a magnetic field is studied. It is shown, that at certain orientations of the magnetic field with respect to the layers the collisionless absorption is ...
  • Size quantization in metal films 
    Nedorezov, S.S. (Физика низких температур, 2007)
    Quantum size effect, predicted by I.M. Lifshits and A.M. Kosevich [Izv. Akad. Nauk SSSR, seriya fiz. 19, 395 (1955)], was investigates in a many works. In the basis of analysis of quantum size oscillations of thermodynamics and ...
  • Collective excitations in dynamics of liquids: a «toy» dynamical model for binary mixtures 
    Bryk, T.; Mryglod, I.M. (Физика низких температур, 2007)
    We propose a new «toy» dynamical model that permits us to derive analytical expressions for dispersion of two branches of «bare» propagating collective excitations in binary disordered systems in the whole range of ...
  • A Monte Carlo study of the Falicov–Kimball model in the perturbative regime 
    Musiał, G.; Dębski, L.; Wojtkiewicz, J. (Физика низких температур, 2007)
    Finite-temperature properties of the Falicov–Kimball model on the square lattice have been studied in the perturbative regime, i.e. for t/U << 1, where t is the hopping constant and U denotes the Coulomb interaction strength. ...
  • Nonequilibrium statistical operators for systems with finite lifetime 
    Ryazanov, V.V. (Физика низких температур, 2007)
    A family of nonequilibrium statistical operators (NSO) is introduced which differ by the system lifetime distribution over which the quasiequilibrium (relevant) distribution is averaged. This changes the form of the ...
  • Fine structure of critical opalescence spectra 
    Sushko, M.Ya. (Физика низких температур, 2007)
    The effect of the 1.5-scattering mechanism on the time and temperature behavior of the electric field autocorrelation function for the light wave scattered from fluids has been studied for the case where the order- parameter ...
