چکیده انگلیسی
We investigate the aging dynamics of colloidal depletion gel by computer simulation. In this study, we employ an alternative approach using the effective pair potential to avoid the slow convergence in binary mixtures due to cage effect, and the structural formation of colloidal depletion gels is then clarified. We study the mean square displacement (MSD) of each segment in depletion gels by stochastic molecular dynamic simulations. It is shown that the MSD obeys a power-law, indicating sub-diffusive behavior of depletion gels. We also observe aging phenomena of the colloidal depletion gels from intermediate scattering functions. Power-law behavior of a characteristic time in this system, as a function of a waiting time, is also clarified.
