Semi-flexible Trimers on the Square Lattice in the Full Lattice Limit
Trimers are chains formed by two lattice edges, and therefore three monomers. We consider trimers placed on the square lattice, the edges belonging to the same trimer are either colinear, forming a straight ro...

Simple model for attraction between like-charged polyions
We present a simple model for the possible mechanism of appearance of attraction between like charged polyions inside a polyelectrolyte solution. The attraction is found to be short ranged, and exists only in ...

Tension of polymers in a strip
We consider polymers, modelled as self-avoiding chains, confined on a strip defined on the square lattice with spacing a in the (x,y) plane, limited by two walls which are impenetrable to the chains and located a...
