Dynamic critical phenomena near a liquid-gas critical point

Gurovich E. V., Kats E. I., Lebedev V. V., Muratov A. R.

The normal-mode spectrum near a liquid-gas critical point is derived. The quantities which appear in the acoustic dispersion relations have a complex critical behavior, which cannot be described by simple scaling laws. Only the first terms of an expansion of the exact equations derived in this paper obey scaling laws. These exact equations are derived by summing infinite series of modified ladder diagrams.
