Abstract: | The mode-mode coupling theoretical expression for the decay rate of order-parameter fluctuations in simple fluids near the critical point is evaluated with the aid of the recently extended Ornstein-Zernike theory. This gives that ψ?ν for the critical-point exponent ψ which characterize the behavior of the thermal conductivity. Also, the results for sound-wave absorption and dispersion near the gas-liquid critical point need not depend on a single reduced frequency variable since scaling may be violated. |
