چکیده

Abstract. Recently it was shown that the introduction of stiffness into the model of self-interacting partially directed walks modifies the polymer collapse transition seen from a second-order to a first-order one. Here we consider the effect of stiffness on the adsorption transition. We provide the exact generating function for non-interacting semi-flexible partially directed walks and analyse the solution in detail. We demonstrate that stiffness does not change the order of the adsorption transition, in contrast to its effect on collapse.

Exact solution of semi-flexible and super-flexible interacting partially directed walks

We provide the exact generating function for semi-flexible and super-flexible interacting partially directed walks and also analyse the solution in detail. We demonstrate that while fully flexible walks have a collapse transition that is second order and obeys tricritical scaling, once positive stiffness is introduced the collapse transition becomes first order. This confirms a recent conjectur...

Exact solution of two friendly walks above a sticky wall with single and double interactions

We find, and analyse, the exact solution of two friendly directed walks, modelling polymers, which interact with a wall via contact interactions. We specifically consider two walks that begin and end together so as to imitate a polygon. We examine a general model in which a separate interaction parameter is assigned to configurations where both polymers touch the wall simultaneously, and invest...

Depletion layers in polymer solutions : influence of the chain persistence length

2014 We propose a simple model for the concentration profile induced by a non-adsorbing solid wall in dilute solutions of semi-flexible chains. Our approach is based on the assumption that the restriction in the chain local curvature of the chain creates a non-zero surface concentration. The monomer concentration profile 03A6SF(Z) is deduced from the mean-field model for flexible chains, 03A6F(...

On directed compact percolation near a damp wall

The percolation probability for directed, compact percolation near a damp wall, which interpolates between the previously examined cases, is derived exactly. We find that the critical exponent β = 2 in common with the dry wall, rather than the value previously found in the wet wall and bulk cases. The solution is found via a mapping to a particular model of directed walks. We evaluate the exact...

An exact solution of two friendly interacting directed walks near a sticky wall

We find the exact solution of two interacting friendly directed walks (modelling polymers) on the square lattice. These walks are confined to the quarter plane by a horizontal attractive surface, to capture the effects of DNA-denaturation and adsorption. We find the solution to the model’s corresponding generating function by means of the obstinate kernel method. Specifically, we apply this tec...
