We study the one-dimensional sine-Gordon model as a prototype of roughening phenomena. In spite of thefact that it has been recently proven that this model cannot have any phase transition @J. A. Cuesta and A.Sánchez, J. Phys. A 35, 2373 (2002), Langevin as well as Monte Carlo simulations strongly suggest theexistence of a finite temperature separating a flat from a rough phase. We explain this result by means of thetransfer operator formalism and show as a consequence that sine-Gordon lattices of any practically achievablesize will exhibit this apparent phase transition at unexpectedly large temperatures.This work was supported by the Ministerio de Ciencia y Tecnología of Spain and FEDER through Grant Nos.
