First-order depinning transition in two-dimensional abraham model: RG approach

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

Using a position-space renormalization group (RG) we analyse the competition for an interface between the boundary defect and an additional line of defect bonds in the two-dimensional Abraham model. The RG phase diagram, obtained over the whole range of temperatures and pinning parameters, indicate that beside the continuous wetting transition this model exhibits a finite-temperature interface depinning transition of the first order in agreement with recently obtained exact results.
