    Cylindrical blast wave with radiation heat flux in self-gravitating gas (1995)
    Springer

    Thema: Physik
    Notizen: Summary A similarity solution of cylindrical shock waves propagating in a uniform atmosphere through self-gravitating gas including the influence of radiation heat flux has been investigated. This problem has also been studied in isothermal conditions. The total energy of the line explosion is assumed to be constant. The solutions of the problem are compared with the results obtained in adiabatic conditions through figures.

    MHD cylindrical shock wave in self-gravitating gas (1995)
    Springer
    Il nuovo cimento della Società Italiana di Fisica 17 (1995), S. 335-342

    Thema: Physik
    Notizen: Summary Similarity solutions of the propagation of cylindrical blast waves through a self-gravitating polytropic gas caused by an instantaneous release of finite energy are investigated theoretically including the influence of transverse magnetic field. A comparative study of the distributions of velocity, density, mass, pressure, temperature and magnetic field has been illustrated through figures.

    Cooper pair breaking and isotope effect coefficient variation in high-T c superconductors (1996)
    Springer
    Journal of superconductivity 9 (1996), S. 269-271 
    Details
    ISSN: 1572-9605
    Schlagwort(e): YBa2Cu3O7 ; pair breaking ; isotope effect
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Elektrotechnik, Elektronik, Nachrichtentechnik , Physik
    Notizen: Abstract The effect of pair breaking on the isotope effect coefficientα=−d lnT c/d lnM in La2−x Sr x CuO4 and Pr-, Ca-, and Zn-doped YBa2Cu3O7−x and EuBa2Cu3O7−x is studied using the generalized Abrikosov-Gorkov theory recently employed by Singh and Kishore for superconductivity. It is argued that the isotope effect coefficientα can be further enhanced, in agreement with experimental observations, by considering the dependence of the characteristic scattering timeτ s for Cooper pairs on the concentrationn of impurities (both magnetic and nonmagnetic) and the disorder ignored by them (J. Supercond. 8, 9 (1995).

    A Possible Explanation of Critical Temperature and Isotope Effect Coefficient of High T c Cuprate Superconductors (1998)
    Springer
    Journal of superconductivity 11 (1998), S. 663-665 
    Details
    ISSN: 1572-9605
    Schlagwort(e): Critical temperature ; isotope effect ; high-T c superconductors ; electron–phonon ; electron–biexciton
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Elektrotechnik, Elektronik, Nachrichtentechnik , Physik
    Notizen: Abstract The expressions for superconducting transition temperature (T c) and isotope effect coefficient (α) have been derived from a generalized integral gap equation for a strongly coupled superconductor, when electrons–phonons and electrons–biexcitons are simultaneously present in high-T c cuprate superconductors.
