Pseudo-first-order transition in interacting self-avoiding walks and trails
The coil–globule transition of an isolated polymer has been well established to be a second-order phase transition described by a standard tri-critical O(0) field theory. We present Monte Carlo simulations of interacting self-avoiding walks and interacting self-avoiding trails in four dimensions which provide compelling evidence that the approach to this (tri)critical point is dominated by the ...
متن کاملFour-dimensional polymer collapse: pseudo-first-order transition in interacting self-avoiding walks
In an earlier work we provided the first evidence that the collapse, or coil-globule transition of an isolated polymer in solution can be seen in a four-dimensional model. Here we investigate, via Monte Carlo simulations, the canonical lattice model of polymer collapse, namely, interacting self-avoiding walks, to show that it not only has a distinct collapse transition at finite temperature but...

متن کاملNature of the collapse transition in interacting self-avoiding trails.
We study the interacting self-avoiding trail (ISAT) model on a Bethe lattice of general coordination q and on a Husimi lattice built with squares and coordination q=4. The exact grand-canonical solutions of the model are obtained, considering that up to K monomers can be placed on a site and associating a weight ω_{i} with an i-fold visited site. Very rich phase diagrams are found with nonpolym...
متن کاملSelf-avoiding walks, neighbour-avoiding walks and trails on semiregular lattices
We study self-avoiding and neighbour-avoiding walks and lattice trails on two semiregular lattices, the (3.122) lattice and the (4.82) lattice. For the (3.122) lattice we find the exact connective constant for both self-avoiding walks, neighbour-avoiding walks and trails. For the (4.82) lattice we generate long series which permit the accurate estimation of the connective constant for self-avoi...
