Random Field Ising Model Criticality in a Complex Binary Liquid System

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The Authors report on experimental studies of a binary mixture in porous medium close to the critical  point of the miscibility transition, and show for the first time for a fluid system that the critical exponents are in agreement with theoretical predictions within the random field Ising model. The analysis of the results is systematic and careful. The article is well written and should be published as is.

This is a very thoroughly conducted SANS study that deals with the determination of critical exponents for a binary liquid system confined in a porous gel. Accurate values of the exponents were obtained, which clearly differed from those of the already published non-confined system and was found to comply with the theoretical description given by the Random field Ising model. The context of the study, the experimental findings and the predictions of the model were comprehensively discussed.

In a nutshell, an excellent work on an original topic that does not need any further improvement. I recommend its acceptation in present form.

Reviewer 3 Report

Comments and Suggestions for Authors  

The paper describes an experimental study of the critical behavior of the 3MP/D2O binary liquid in an aerogel. The aerogel is not named in the paper; it is probably a silica aerogel, and I suggest specifying this.

In my view, the experimental procedure and the data evaluation are adequate, and the conclusions are correct. Therefore, I consider the manuscript suitable for publication as it is.
