Research Topic

Polymer Physics

The fundamental understanding of the thermophysical and dynamic properties of polymer systems are very important to their use in industrial applications and future development of materials. The goal of my research is to utilize computer simulations as well as statistical-mechanics based theories to obtain detailed information microscopically and thus provide a deeper understanding of the physical behavior of polymer systems.


 

Thermodynamically Equilibrium Systems with Charged Interfaces

Many biological and colloidal systems involve the electrostatic interaction, which decays inversely proportional to the interparticle distance. Such long-range nature renders the studies of electrolyte systems challenging. We embark on our investigation from the mean-field theory such as Poisson-Boltzmann equation. Detailed knowledge, such as ion fluctuations and correlations, is obtained by molecular simulations based on the primitive model.
