Partition function for several Ising model interface structures
Alessio Squarcini, Piotr Nowakowski, Douglas B. Abraham +1
We employ a procedure that enables us to calculate the excess free energies for a finite Ising cylinder with domain walls analytically. This procedure transparently covers all poss…
Surface fields and emergence of long-range couplings in classical uniaxial ferromagnetic arrays
D. B. Abraham, A. Maciolek, A. Squarcini
Critical wetting is of crucial importance for the phase behaviour of a simple fluid or Ising magnet confined between walls that exert opposing surface fields so that one wall favou…
Critical Casimir interaction between colloidal Janus-type particles in two spatial dimensions
Alessio Squarcini, Anna Maciołek, Erich Eisenriegler +1
We study colloidal particles with chemically inhomogeneous surfaces suspended in a critical binary liquid mixture. The inhomogeneous particle surface is composed of patches with al…
Ensemble dependence of Critical Casimir Forces in Films with Dirichlet Boundary Conditions
Christian M. Rohwer, Alessio Squarcini, Oleg Vasilyev +2
In a recent study [Phys. Rev. E \textbf{94}, 022103 (2016)] it has been shown that, for a fluid film subject to critical adsorption, the resulting critical Casimir force (CCF) may…
Action at a distance in classical uniaxial ferromagnetic arrays
D. B. Abraham, A. Maciołek, A. Squarcini +1
We examine in detail the theoretical foundations of striking long-range couplings emerging in arrays of fluid cells connected by narrow channels by using a lattice gas (Ising model…
