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…

Action at the distance
D. B. Abraham, A. Maciolek, O. Vasilyev
We present a system exhibiting giant proximity effects which parallel observations in superfluid helium (Perron et al, Nature Physics V. 6, 499 (2010)) and give a theoretical expla…
