    Notes: [Auszug] IN a previous communication1, the formation of a high degree of acidity (pH 1.7–1.8) during fermentation by ordinary bakers’ yeast was described. Acid formed to this extent in the suspending fluid (0.6 part to 1.0 of yeast) when unbuffered and containing potassium chloride of ...

    Steady state solutions of master equations without detailed balance (1976)
    Springer
    The European physical journal 25 (1976), S. 423-427 
    Details
    ISSN: 1434-6036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Steady state solutions of master equations with one variable are constructed. The method of solution is based on a transformation of the original equation for the probability into one for a slowly varying function. The method is of general applicability and is particularly useful in obtaining solutions in the case where detailed balance does not hold. Examples of such systems in chemical reaction models and the two photon laser are discussed.

    Detailed balance in open quantum Markoffian systems (1976)

    Details
    ISSN: 1434-6036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Agarwal's definition of detailed balance for open quantum Markoffian systems is shown to arise from microreversibility in an analogous fashion to the familiar classical concept. It is therefore presented as the appropriate formal generalisation of the classical result to the quantum-mechanical regime. This fully quantum-mechanical approach is discussed in relation to the Fokker-Planck equations of the phase-space calculus and the Pauli master equation; two contexts in which a pseudo-classical form of detailed balance is well known. Our discussion is illustrated through the examples of the damped harmonic oscillator and the single mode laser.

    Quantum dynamics of bouncing atoms in a stable gravitational cavity (1995)
    Springer
    Applied physics 60 (1995), S. 211-227 
    Details
    ISSN: 1432-0649
    Keywords: 32.80.Pj
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Two-level atoms bouncing in a stable gravitational cavity are considered, where the atomic mirror at the bottom of the bounces is an evanescent wave caused by an internally reflected intense Gaussian-mode laser beam. We consider the broadening mechanisms of the atoms from their initially tightly spaced position distribution, using a phenomenological semi-classical model, which includes spontaneous emission. A fully quantum model, which neglects spontaneous emission, is derived, and the broadening of the atomic wave function in the quantum model is compared with the broadening of the atomic distribution in an analogous classical simulation where spontaneous emission is similarly neglected. We find that the broadening is correctly described by the classical simulations in the horizontal directions, while it significantly underestimates the broadening in the vertical direction.

    QND measurements using dual ported cavities (1997)
    Springer
    Applied physics 64 (1997), S. 225-233 
    Details
    ISSN: 1432-0649
    Keywords: PACS: 42.50 Lc
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract.  Optical QND measurements may be made using devices which act as nonlinear beam splitters, transmitting noise in a phase-sensitive way. One class of such devices are resonant optical cavities containing a nonlinear medium. By appropriate choice of nonlinearity and operating parameters, various QND observables may be measured. We consider, in particular, the extent to which the QND performance of these devices is degraded by intracavity losses.

    Coupled Stokes and Antistokes radiation in Raman scattering (1971)
    Springer
    Optical and quantum electronics 3 (1971), S. 57-60 
    Details
    ISSN: 1572-817X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract An analysis of the coupled Stokes and Antistokes radiation in Raman scattering, including laser depletion, is found to predict a finite gain at perfect momentum matching. This is in contradiction to the results of Bloembergen and Shen who treated the laser as a constant and hence predicted zero gain at perfect momentum matching.
