In the last decade, there has been growing interest in the condensation behavior of biomolecules, especially following the demonstration of its biological implications, such as the reversible formation and dissociation of membraneless cellular organelles. Particularly, since the concept of the "super-enhancer" was introduced, the role of biomolecular condensation in chromatin dynamics has been intensively investigated. In this talk, I will briefly introduce recent advances in our understanding of biomolecular condensation, focusing on its role in chromatin dynamics, and discuss how traditional polymer models can provide insight into this area.
