Correlations and structure of interfaces in the Ising model: theory and numerics

A Squarcini, A Tinti - Journal of Statistical Mechanics: Theory and …, 2021 - iopscience.iop.org
We consider phase separation on the strip for the two-dimensional Ising model in the near-
critical region. Within the framework of field theory, we find exact analytic results for certain …

Shape and interfacial structure of droplets. Exact results and simulations

A Squarcini, A Tinti - Journal of Statistical Mechanics: Theory and …, 2023 - iopscience.iop.org
We consider the fluctuating interface of a droplet pinned on a flat wall. For such a system we
compare results obtained within the exact field theory of phase separation in two dimensions …

Interfacially adsorbed bubbles determine the shape of droplets

A Squarcini, A Tinti - SciPost Physics, 2023 - scipost.org
The characterization of density correlations in the presence of strongly fluctuating interfaces
has always been considered a difficult problem in statistical mechanics. Here we study-by …

Wetting and emergence of long-range couplings in arrays of fluid cells

DB Abraham, A Maciołek, A Squarcini - Physical Review E, 2024 - APS
Critical wetting is of crucial importance for the phase behavior of a simple fluid or Ising
magnet confined between walls that exert opposing surface fields so that one wall favors …
