Abstract
We employ flat energy interacting growth walk (flatIGW) algorithm to estimate accurately the density of states of an interacting self avoiding walk on a face centered cubic lattice. Using the computed density of states, by analysing the specific heat and zeros of the partition function, we show that interacting self avoiding walk on face centered cubic lattice exhibits a second order coil globule transition. The accuracy of flatIGW in estimating density of states allows us to determine the theta temperature accurately even with walks of short walk lengths.
