Thermodynamics of domain walls and the phase transition in the d-dimensional one-component φ4-model
S. B. Rutkevich · Soviet Journal of Low Temperature Physics · 1990
The possibility of phase transition associated with spontaneous formation of domain walls is investigated in the classical one-component φ4-model on a d-dimensional (d ≥ 2) lattice in the continuous limit (the lattice spacing is much smaller than the correlation length at zero temperature). It is shown that such a transition does not occur at any temperature with the exception, perhaps, of the vicinity of the diplacement phase transition temperature.
