Profile

Professor Haataja's research focuses on theoretical and computational materials science, physics of materials, and physical biology.  Current work includes studies of microstructure formation during solid-solid phase transformations and solidification, growth of electrodeposited thin films and quantum heterostructures, dynamics of driven interfaces in the presence of mobile impurities,  recrystallization kinetics, signaling in cells, and regulation & self-organization of "lipid rafts" in the plasma membrane

RESEARCH GROUP


We have recently studied the dynamics of interfaces in an Ising model coupled to diffusing impurities. We have shown that the behavior of the system can be described (in a certain limit) in terms of an effective free-energy which decribes the kinetics of impurities attaching to and detaching from the interface.

The figure above shows typical pinned configuration where the local impurity density along the interface is very large. More details can be found in M. Haataja et al., PRL 92, 160603 (2004).
