Four-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 کاملFour-dimensional polymer collapse II: Interacting self-avoiding trails
We have simulated four-dimensional interacting self-avoiding trails (ISAT) on the hypercubic lattice with standard interactions at a wide range of temperatures up to length 4096 and at some temperatures up to length 16384. The results confirm the earlier prediction (using data from a non-standard model at a single temperature) of a collapse phase transition occurring at finite temperature. More...
متن کاملPseudo-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 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...
