}The unbinding of three strings in a plane which interact via short-ranged attractive potentials is studied using both transfer-matrix methods and Monte Carlo techniques. In the symmetric case, for which the two outer strings have the same line tension, the critical behavior depends on the relative flexibility of the inner string in a nonuniversal fashion. In the asymmetric case, the strings unbind in two successive unbinding transitions at two different temperatures. Renormalization-group…

The unbinding transition of three strings, fluctuating without overhangs in two dimensions, is considered in the Born-Oppenheimer approximation. The calculation, which is extremely simple, gives some…

A 1+1 dimensional model of n nonintersecting strings with short-range attractive interactions on a lattice is solved exactly. For arbitrary finite n>2 there is a second-order binding-unbinding…

This work has shown that for freely suspended bunches, all membranes unbind simultaneously at a unique N-independent temperature T*s, but the effective critical behaviour depends on N over many length scales.
