Critical behavior of a fluid in a disordered porous matrix: An Ornstein-Zernike approach
arXiv:cond-mat/9504023 · doi:10.1103/PhysRevLett.74.4361
Abstract
Using a liquid-state approach based on Ornstein-Zernike equations, we study the behavior of a fluid inside a porous disordered matrix near the liquid-gas critical point.The results obtained within various standard approximation schemes such as lowest-order $γ$-ordering and the mean-spherical approximation suggest that the critical behavior is closely related to that of the random-field Ising model (RFIM).
