ICMT Seminar: "Pattern Formation from Competing Interactions: Implications for Soft and Hard Condensed Matter Systems"
I will give an overview of how systems with competing interactions such
as repulsion on one scale and attraction
on another can generically give rise to bubble, stripe, clump, and other
patterns. The same patterns can occur for systems with purely repulsive
interactions provided there are two or more distinct length scales in
the potential. I will show how these patterns can arise in soft matter
systems, charge ordered systems, neutron stars in the form of pasta
phases, and vortex states in multi-band superconductors. Under
application of an external drive these systems can also exhibit numerous
nonequilibrium phase transitions that produce pronounced changes in the
transport properties. I will also discuss how pattern formation in these
systems can be influenced by a patterned substrate such as a periodic
array of two-dimensional pinning sites.
