С 12 по 18 августа 2002 г. в Научном центре Черноголовка РАН проходил 3-й Международный семинар по физике низких температур в условиях микрогравитации CWS-2002. По традиции семинар CWS-2002 был включен в список сателлитных конференций и семинаров, посвященных одному из быстро развивающихся направлений в физике низких температур, которые сопутствуют проводимой раз в три года Международной конференции по физике низких температур. 2003-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/128874 Thermal expansion of solid solutions Kr-CH₄ at temperatures of liquid helium Aleksandrovskii, A.N.; Gavrilko, V.G.; Dolbin, A.V.; Esel`son, V.B.; Manzhelii, V.G.; Udovidchenko, B.G. A negative contribution of the CH₄ impurity to the thermal expansion of the solution has been revealed in the dilatometric studies of solid Kr + 0.76% CH4, Kr + 5.25% CH₄, and Kr + 10.5% CH₄ solutions at 1-23 K. It is shown that the negative contribution results from changes in the occupancy of the ground state of the A-modifications of isolated CH₄ molecules. Assuming that the CH₄ impurity singles and clusters contribute to the thermal expansion independently, we can estimate their contributions. The contribution of the singles to the thermal expansion of the solid solution is negative. The energies of the first excitational rotational states were determined for singles and two-body and three-body clusters of the CH₄ molecules. 2003-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/128873 Vibrational dynamical and thermodynamical characteristics of the superlattices based on the metal-hydrogen system Feodosyev, S.B.; Gospodarev, I.A.; Grishaev, V.I.; Syrkin, E.S. The phonon spectra and vibrational thermodynamical characteristics of the Pd-H superlattices are investigated. Results of our calculations give a possibility to agree the data of neutronographic and calorimetric experiments and explain for the such systems the atomic mean square amplitudes and correlations between ones. 2003-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/128872 Quantum computing with bits made of electrons on a helium surface Dahm, A.J. 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 trapped in the image potential well at the surface. Mechanisms for preparing the initial state of the qubit, operations with the qubits, and a proposed readout are described. This system is, in principle, capable of 10⁵ operations in a decoherence time. 2003-01-01T00:00:00Z
