  • Levitation of delocalized states at weak magnetic field: critical exponents and phase diagram 
    Kagalovsky, V. (Физика низких температур, 2013)
    We study numerically the form of the critical line in the disorder–magnetic field phase diagram of the p–q network model, constructed to study the levitation of extended states at weak magnetic fields. We use oneparamet ...
  • Librational motion of CO in solid Ar: Raman and IR spectra and quantum simulations

    The appearance of new phonon lines in the Raman spectrum of the quasi-one-dimensional antiferromagnet CsFeCl₃·2H₂O as a consequence of magnetic ordering with a change of the unit cell volume was detected experimentally. ...
  • Linear, diatomic crystal: single-electron states and large-radius excitons 
    Adamyan, V.M.; Smyrnov, O.A. (Физика низких температур, 2009)
    The large-radius exciton spectrum in a linear crystal with two atoms in the unit cell was obtained using the single-electron eigenfunctions and the band structure, which were found by the zero-range potentials method. The ...
  • Liquid ³He–⁴He mixture phase diagram in restricted geometry 
    Degtiarov, I.A.; Sokolov, S.S. (Физика низких температур, 2012)
    The influence of van der Waals forces on the decay of liquid solutions of helium isotopes is studied theoretically and the conditions for the phase co-existence in a confined geometry are investigated. As the models to ...
  • Local and global superconductivity in bismuth 
    Baring, L.A.; da Silva, R.R.; Kopelevich, Y. (Физика низких температур, 2011)
    We performed magnetization M(H,T) and magnetoresistance R(T,H) measurements on powdered (grain size ~ 149 μm) as well as highly oriented rhombohedral (A7) bismuth (Bi) samples consisting of single crystalline blocks of ...
  • Local field effects in the spectroscopy of Cs atoms trapped in solid ₄He

    The H + Ar + F reaction leading to HArF formation in an argon matrix is studied at temperatures down to 8 K. The effects of the precursor concentration, deuteration, IR light, and deposition temperature as well as thermal ...
