Dynamic fluctuation effects in soap films
Dynamic fluctuation phenomena in free-standing soap films are investigated. It is shown that the squeezing mode (where the water is pumped back and forth) induces contributions to kinetic coefficients (viscosity and diffusion) which are divergent at the intermediate scales, leading to anomalous scaling behavior of the coefficients. The corresponding exponents are calculated using RG methods in the one-loop approximation. They are e/19 and 18e/19 where e = 4 — d, and d is the dimensionality of the space (the physical value being d=2). The role of bending fluctuations is also discussed.
