Transições ele fase em um modelo de crescimento interagente semiflexível

Abstract: O modelo de crescimento cinético interagente (Interacting Growth Walk -IGW) pertence a uma classe de modelos de crescimento usada para simular processos de polimerização. Ele gera cadeias auto-exclusivas que podem ser usadas no estudo de propriedades de cadeias poliméricas em diferentes temperaturas. Neste trabalho o modelo de crescimento interagente de Narasimhan e cois, foi generalizado para levar em conta efeitos da energia gasta para promover dobras durante a formação da cadeia. Para isso um fator de rigid… Show more

“…However, those configurations are necessary for investigation of phase transition of linear polymers, especially at low temperature [40]. To overcome this shortcoming, a new kinetic method for generating ISAW configurations, called as Interacting growth walk (IGW), was proposed [41][42][43][44]. For IGW, it has been shown that the ensemble average of atmosphere (see below) gives an estimate of DoS [21].…”

“…The interaction is inserted in the model using the Boltzmann factor β = 1/kT [23], so the effects compete with the temperature T . A second type of interaction is the folding one, which deals with the tendency of having straight lines on the chain [29,30]. When two interactions are added simultaneously on the model, the competition between them will define the phase of the system.…”
