AVVISO DI SEMINARIO Dr. Cristiano De Michele: Soft Mesophases
Colloidal systems can be challenging to study due to the presence of multi scale effects, extending from tenth of nanometers (solvent) up to sub-micro particle-particle correlations.
Multi-scale approach combining theory and computer simulations provides a suitable framework for modelling these systems.
At the bottom level, atomistic simulations of macromolecules are performed to estimate parameters that serve as inputs for the theory or for coarse-grained models.
After that, affordable computer simulations of minimalist models or the theoretical machinery are put in action to provide quantitative predictions on the system under investigation. In the talk, I will focus on two recent developments:
(i) a theoretical approach for calculating the elastic and thermodynamic properties of liquid crystals and
(ii) a coarse-grained model of epoxy resins which allowed to afford theoretical insight into autocatalytic reactions.
In passing, I will also discuss novel algoithms which I developed for carrying out fast computer simulations. Finally, I will discuss an interesting analogy between Abrikosov vortices and colloidal systems, which makes soft matter physics more ubiquitous than expected.
