“…We have studied the critical dynamics of the system 3methyl pyridine (3MP) / D 2 O without and with antagonistic salt [1]. We found a 3d-and 2d-Ising behavior in the static structural measurements (also firstly found in [2,3]) and a characteristic critical behavior for the dynamics [1].…”

“…We argued [1] that the finite viscosity that applies for the two lateral dimensions manages to avoid the third dimension for shorter times (when one could speculate about the Pomeau divergence [16]) but at later stages the molecules enter the third dimension when the charge density waves come into play. In the experiments with strong contrast between 3MP and D 2 O the whole influence of the charge density waves appears rather low.…”

Here we focus on the high-Q small-angle neutron scattering where we observed deviations from an ideal power law Q−2. From theory, this deviation Δ arises from the critical correlation-function exponent ηd in d dimensions. The investigated systems were 3-methyl pyridine/D2O without and with antagonistitc salt. They display the critical behavior of a 3d and 2d Ising system, respectively. In the first case, the value of Δ matches the ideal value η3 well, but in the latter case the value of Δ is affected by the two confined dimensions and the third dimension.

While Ising criticality in classical liquids has been firmly established both theoretically and experimentally, much less is known about criticality in liquids in which the growth of the correlation length is frustrated by finite-size effects. A theoretical approach for dealing with this issue is the random-field Ising model (RFIM). While experimental critical-exponent values have been reported for magnetic samples (here, we consider γ, ν and η), little experimental information is available for critical fluctuations in corresponding liquid systems. In this paper, we present a study on a binary liquid consisting of 3-methyl pyridine and heavy water in a very light-weight porous gel. We find that the experimental results are in agreement with the theoretical predictions from the RFIM.
