Abstract
The organization of a large collection of particles into an ordered
crystalline array is needed for many applications, including pharmaceutical
separations, nuclear waste disposal, and optoelectronic metamaterials. Due to
improvements in sensing technology, it is now becoming possible to monitor the
crystalline state in real time during the crystallization process, and this sensor
technology opens up new possibilities for feedback control. Here we monitor the
crystalline state and use this data to build an empirical model. An optimal
feedback policy is then calculated using the empirical model along with dynamic
programming. Alternatively, the empirical model can be calculated from simulation
“data” coming from a detailed particle-level simulation. Experimental results
demonstrating the method will be presented for molecular crystallization and
colloidal crystallization.
