    Notes:
    The self-diffusion of particles in the two-dimensional square lattice gas with nearest-neighbor exclusion is investigated. At high concentration the diffusion is severely hindered by kinetic constraints. The resulting pattern of cooperativity is analyzed and found to be parallel to that observed in the two-spin facilitated kinetic Ising model of Fredrickson, Andersen, and Brawer. It is argued that a blocking transition does not exist in the thermodynamic limit. The argument, which is based on the calculation of the percolation probability in the "rectangular-cluster percolation problem,'' is confirmed by Monte Carlo calculations of the mean-square displacement.

    Abstract For field operatorsA,B of Fermion-type variational principles are formulated. The stationary values of the functionals are equal to the Laplace transforms of the retarded and the advanced Green's functions $$\frac{1}{i}\left\langle {\{ A(t),B^ + \} } \right\rangle $$ fort〉0 and $$ - \frac{1}{i}\left\langle {\{ A(t),B^ + \} } \right\rangle $$ fort〈0, respectively. From these functionals new ones are deduced, having extremal properties (a maximum and a minimum principle) and determining $$\frac{1}{i}\left\langle {\{ A(t),B^ + \} } \right\rangle $$ at their extremal values. By the Ritz variational method the stationary principle is used to derive a prescription for approximating Green's functions. In the case of the BCS-Hamiltonian we get the very same results as the BCS-theory without any further assumption about breaking the particle number invariance or introducing quasi averages.

    Abstract The Eliashberg function and the electron-phonon coupling constant fora-Ga are calculated in the framework of the free-electron model, using measured sound velocities and resistivity data for the normal state. In particular, the contribution of the soft transverse acoustic phonons is estimated. For phonon frequencies up to 300 GHz, it amounts to not more than 5% of the total coupling constant.

    Notes:
    Abstract We derive an expression for the low-temperature electrical resistivity in simple monovalent metals caused by electron-impurity and electron-phonon scattering. Since the recent measurements of the electrical resistivity of van Kempen et al. give direct evidence for the existence of phonon drag we take phonon drag into account. Our expression is exact in the limit of strong electron-impurity scattering. For the model of an acoustically isotropic metal we obtain a simple analytical formula which reproduces the experimental data on potassium fairly well, with both fitparameters, the sound velocity and the pseudopotential, being close to the values expected from other data.

    Zusammenfassung 1. Es wurden die bei Benutzung von Schweißlederersatz hervorgetretenen Mißstände besprochen und Richtlinien für die Herstellung einwandfreier Fabrikate gegeben. 2. Es wurde dargelegt, worauf sich die Untersuchung von Schweißlederersatz zu erstrecken hat. 3. Eine besonders für die Isolierung von Phenol und Kresol aus imitiertem Schweißleder geeignete Methode wurde mitgeteilt. 4. Die gebräuchlichsten Reaktionen auf Phenol und Kresol wurden einer Prüfung auf Zuverlässigkeit in Gegenwart der im Schweißlederersatz vorkommenden störenden Stoffe unterzogen, teilweise abgeändert und die Art angegeben, wie sie am geeignetsten auszuführen sind. 5. Zum Schluß wurden Gesichtspunkte für die Untersuchung phenolfreien Schweißlederersatzes entwickelt.
