Abstract:

In this article, the critical exponents of the polymer model Self Avoiding Trail (SAT) in three dimensional simple cubic lattice and face centered cubic lattice have been studied using Monte Carlo simulation method. The results obtained show that the critical exponents of SAT or its behaviors are intermediate between those of SAW and RW, so it is impossible for SAT to belong to the same universal class with SAW.

Key words: Self-Avoiding Trail(SAT), Critical exponent, Simple cubic lattice, Face-centered cubic lattice, Partition function, Universal class
