Consider a polymer chain dissolved in a solvent, where its behavior is influenced by the Flory parameter, denoted by $\chi$. As the interaction parameter $\chi$ varies, the chain undergoes several conformational transitions: • For $\chi > \chi_c$, the polymer collapses into a dense, globular structure with a radius of gyration scaling as $R_g \sim N^{1/3}$. • At […]
