Thermodynamic properties of interacting like-rod chains: Entropic sampling simulations

Abstract In this work we apply the transfer matrix method to obtain exact solutions for a rod-like interacting unidimensional system and carry out entropic simulations to obtain the same results. A joint density of states is adopted, such that it depends not only of the energy, but also of the total number of dimers and the number of interactions between interacting dimers. We estimate the density of dimers and vacancies, along with the number of interacting links per site, and compare with the exact results. The concordance is excellent.
