  • Biexcitons in solid neon 
    Wiethoff, P.; Kassühlke, B.; Menzel, D.; Feulner, P. (Физика низких температур, 2003)

  • Coherent motion and anomalous transport properties of exciton and hole polarons with intrinsic vibrationa 
    Ratner, A.M. (Физика низких температур, 2003)
    It is shown that intrinsic vibrational degrees of freedom, inherent in two-atom exciton and hole polarons, drastically affect their transport properties in wide-band dielectrics (rare-gas solids and alkali halides). A fast ...

    The optical and magneto-optical (MO) spectra of the ternary compound UCuAs₂ are investigated theoretically from first principles, using the fully relativistic Dirac linear-muffin-tin-orbital band structure method. The ...
  • Element-specific and site-specific ion desorption from adsorbed molecules by deep core-level photoexcitation at the K-edges 
    Yuji Baba (Физика низких температур, 2003)
    This article reviews our recent works on the ion desorption from adsorbed and condensed molecules at low temperature following the core-level photoexcitations using synchrotron soft x-rays. The systems investigated here ...

    Klier, J.; Schletterer, F.; Leiderer, P.; Shikin, V. (Физика низких температур, 2003)
    For the thickness of a liquid or solid quantum film, like liquid helium or solid hydrogen, there exist still open questions about how the film thickness develops in certain limits. One of these is the thick film limit, ...
  • ESR investigation of hydrogen and deuterium atoms in impurity-helium solids 
    Kiselev, S.I.; Khmelenko, V.V.; Bernard, E.P.; Lee, D.M. (Физика низких температур, 2003)
    Impurity-helium solids (Im-He solids) are porous solids created by injecting a beam of mixed helium and impurity gases into superfluid ⁴He. In this work we use electron spin resonance (ESR) techniques to investigate Im-He ...
