  • Quantum computing with bits made of electrons on a helium surface 
    Dahm, A.J. (Физика низких температур, 2003)
    We describe a quantum computer based on electrons supported by a helium film and localized laterally by small electrodes. Each quantum bit (qubit) is made of combinations of the ground and first excited state of an electron ...

    Bass, Andrew D.; Sanche, Leon (Физика низких температур, 2003)
    We review recent research on reactions (including dissociation) initiated by low-energy electron bombardment of monolayer and multilayer molecular solids at cryogenic temperatures. With incident electrons of energies below ...

    The linear expansion coefficients of solid bulk samples of N₂O with Kr 5% impurity are measured by an absolute dilatometric method in comparison with pure N₂O in the temperature range 80–150 K. An additional unusual ...
  • Short-range inverse-square law experiment in space 
    Strayer, Donald M.; Paik, Ho Jung; Moody, M. Vol (Физика низких температур, 2003)
    The objective of ISLES (inverse-square law experiment in space) is to perform a null test of Newton`s law on the ISS with a resolution of one part in 10⁵ at ranges from 100 mm to 1 mm. ISLES will be sensitive enough to ...
  • Simulation of stochastic vortex tangle 
    Kondaurova, L.P.; Nemirovskii, S.K.; Nedoboiko, M.V. (Физика низких температур, 2003)
    We present the results of simulation of the chaotic dynamics of quantized vortices in the bulk of superfluid He II. Evolution of vortex lines is calculated on the base of the Biot-Savart law. The dissipative effects appeared ...
  • Soft landing of size selected clusters in rare gas matrices 
    Lau, J.T.; Ehrke, H.-U.; Achleitner, A.; Wurth, W. (Физика низких температур, 2003)
    Soft landing of mass selected clusters in rare gas matrices is a technique used to preserve mass selection in cluster deposition. To prevent fragmentation upon deposition, the substrate is covered with rare gas matrices ...
  • Static skin effect in organic metals 
    Kirichenko, O.V.; Peschansky, V.G.; Savel`eva, S.N. (Физика низких температур, 2003)
    We have studied theoretically galvanomagnetic phenomena in layered conductors of organic origin with multi-sheet Fermi surface being of the form of a weakly corrugated cylinder and weakly corrugated planes. It is shown ...
  • Structural fluctuations and aging processes in deeply frozen proteins 
    Schlichter, J.; Ponkratov, V.V.; Friedrich, J. (Физика низких температур, 2003)
    Frozen proteins are nonergodic systems and are subject to two types of structural motions, namely relaxation and fluctuation. Relaxation manifests itself in aging processes which slow the fluctuations. Within certain ...
  • Structural peculiarities of quench-condensed pure and argon-doped nitrous oxide 
    Solodovnik, V.V.; Danchuk, A.A. (Физика низких температур, 2003)
    Electron diffraction studies have been carried out for condensed N₂O and N₂O–Ar films. Deposition took place at substrate temperatures of 10 and 20 K. The growth process of N₂O deposits was studied. A strong effect of argon ...
  • Structures and optical properties of solid hydrogen at ultrahigh pressures 
    Hitose Nagara (Физика низких температур, 2003)
    We have studied the electronic energy bands for the structures whose primitive cell contains up to four molecules, with full optimization of the structures, based on the GGA and LDA band calculations. Above 250 GPa, the ...
  • Superradiance of J-aggregates: correspondence between infinite disordered chain and regular chain of finite length 
    Ratner, M.A. (Физика низких температур, 2003)
    The radiation decay of excitons in a slightly disordered molecule chain is considered. The degree of disordering dictates the excitonic state length that determines the enhancement of the decay rate Г (superradiance). Г ...
