Spontaneous imbibition in disordered porous solids: a theoretical study of helium in silica aerogels
F. Leoni, E. Kierlik, M. L. Rosinberg +1
We present a theoretical study of spontaneous imbibition of liquid 4He in silica aerogels focusing on the effect of porosity on the fluid dynamical behavior. We adopt a coarse-grai…
Helium condensation in aerogel: avalanches and disorder-induced phase transition
F. Detcheverry, E. Kierlik, M. L. Rosinberg +1
We present a detailed numerical study of the elementary condensation events (avalanches) associated to the adsorption of He in silica aerogels. We use a coarse-grained lattice-…
Local mean-field study of capillary condensation in silica aerogels
F. Detcheverry, E. Kierlik, M. L. Rosinberg +1
We apply local mean-field (i.e. density functional) theory to a lattice model of a fluid in contact with a dilute, disordered gel network. The gel structure is described by a diffu…
A self-consistent Ornstein-Zernike approximation for the Edwards-Anderson spin glass model
E. Kierlik, M. L. Rosinberg, G. Tarjus
We propose a self-consistent Ornstein-Zernike approximation for studying the Edwards-Anderson spin glass model. By performing two Legendre transforms in replica space, we introduce…
