Replica dipolar fluid

Keywords Replica Ornstein-Zernike equation, partially quenched systems, dipolar fluids,... 

Dipolar fluid excess chemical potential. A closed expression for the evaluation of this quantity can be easily derived in the HNC approximation using Lee s star function technique [27] and the replica trick [18], leading to... 

The effect of the variation of on the stability limits of a polar Stock-mayor fluid, which implies a variation of the dipolar fluid matrix coupling, is illustrated in the upper part of Fig. 7.4. All results correspond to dilute matrices that do not suppress the gas liquid transition but lead to a significant shift of that transition. In particular, the critical temperature decreases with increasing p.,n, whereas the critical density increases. This characteristic effect is referred to as preferential adsorption in other contexts. The replica integral equation results thus demonstrate, at a microscopic level, that polar... 

Finally, C tld /,.[ = cdd = c Jm is the Fourier transform of the replica-replica direct correlation function (blocking function), and the connected function is defined as usual by cc = cdd — cdd, and similarly for hc. Let us recall that the replicated particles are the dipolar hard spheres, i.e. the annealed fluid in the partly quenched mixture.
