By means of a continuum approximation introduced in a preceding paper, we present a more transparent treatment of the critical phenomena in the specific heat of a two-dimensional Ising model with a “layer” type spatial inhomogeneity of its exchange coupling. This calculational procedure...

A previously-developed second-quantization representation for nonrelativistic systems of composite bound states and their constituents is extended to any number of composite species. The result is an explicit representation for the kinematics and dynamics of reactive scattering processes...

We have derived 10th order series expansions for the free energy and 9th order ones for the fluctuation of the order parameter in the spin-SXY-model on the f.c.c. lattice for S = 12, 1, 32, 2, 3, 4, 6 and 8. Confluent singularity analyses of the fluctuation series confirm the universality...

Measurements are reported of the change in the thermal conductivity coefficients ▵λ∥ and ▵λ⊥ of polar gases under the influence of a magnetic field at room temperature. Investigated are the linear molecules HCl, DCl, HCN, OCS and CO2 and the symmetric top molecules CH3F, CD3F, CH3CN,...

The current induced Kerr effect in the presence of a homogeneous magnetic field is treated for binary mixtures of neutral molecules and ions. The starting point is a system of moment equations derived from the linearized Waldmann-Snider equation. The dialectric tensor is calculated and studied...

The paper reports accurate measurements of the viscosity of the eighteen binary gaseous systems: CF4 with He, Ne, Ar, N2, CO2, CH4; SF6 with He, Ne, Ar, N2, CO2, CH4, CF4 and O2 with He, Ne, CO2, CF4, SF6. The measurements were performed in a high-precision oscillating-disk viscometer at...

For (eve) and (evμ) binary mixtures the transport coefficients are evaluated as functions of the temperature and composition of the system. The particles are assumed to interact according to the Weinberg-Salam model. Results for the two mixtures are compared, and are contrasted to corresponding...

The tensor and Faddeev-Popov ghost Green's functions of gauge supersymmetry are examined when the spontaneous breaking preserves global supersymmetry. The conditions imposed by global supersymmetry are obtained and integrated. The asymptotic behavior of the unperturbed Green's functions in the...

We compare eight possible definitions of the surface thickness for two density profiles. One definition is eliminated, and then the 10–90 thickness t is shown to be in satisfactory agreement with the other six. Our earlier work on the liquid-vapour interface is taken further, with a physical...

Effects of the potential range of interaction to critical behaviors of anisotropic cubic systems are investigated by means of the Callan-Symanzik equations. As the static critical behavior the stability of fixed points, the critical exponents ηC, γC, φCs and φCc, and the equation of state...
