    Renormalized theory of the time-dependent pair distribution function. I. General formulation (1976)
    Springer
    Journal of statistical physics 15 (1976), S. 59-71 
    Details
    ISSN: 1572-9613
    Keywords: Renormalized kinetic theory ; correlation functions ; time-dependent pair-distribution function
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A classical renormalized theory of a time-dependent pair-distribution function (TDPDF), previously introduced by Oppenheim and Bloom, is presented. An equation of motion for the TDPDF is derived in which the memory function of the system appears. This is then split into a part which contains only static correlation functions and a part which describes the dynamics. The mean field approximation is discussed in some detail and contact is made witn the theory of Oppenheim and Bloom.

    Kinetic theory of vibrational relaxation in a radiation field: The optic-acoustic effect (1973)
    Springer
    Journal of statistical physics 8 (1973), S. 57-78 
    Details
    ISSN: 1572-9613
    Keywords: Kinetic theory ; radiation-driven systems ; rate equations ; vibrational relaxation ; optic-acoustic effect

    Topics: Physics
    Notes: Abstract A microscopic derivation is presented of the rate equations governing vibrational relaxation occurring in the optic-acoustic effect. Detailed expressions applicable to the spectrophone experiment are given both for an excitation source consisting of a broadband radiation field and for laserdriven systems. It is clear from the present treatment that no real advantage accrues from the use of laser excitation sources in the standard spectrophone experiment, due to the resultant strong dependence of the driving force itself on the mechanical chopper frequency. For broadband radiation field the dependence on the chopper frequency is removed and the standard result containing the Einstein coefficient of induced absorption is recovered. The spectrophone response for the simplest case of a two-level system is given explicitly and its similarity to phenomenologically derived expressions is pointed out.
