Confined space and effective interactions of multiple self-avoiding chains
Suckjoon Jun, Axel Arnold, Bae-Yeun Ha
We study the link between three seeming-disparate cases of self-avoiding polymers: strongly overlapping multiple chains in dilute solution, chains under spherical confinement, and…
Remarks on Flory theory of a self-avoiding chain under cylindrical confinement
Suckjoon Jun, Bae-Yeun Ha
Despite its limitations, mainly due to its simplicity, Flory theory has been extended to many other important cases, e.g., linear chains with stiffness and polymers of various topo…
Stabilization/destabilization of cell membranes by multivalent ions: Implications for membrane fusion and division
Bae-Yeun Ha
We propose a mechanism for the stabilization/destabilization of cell membranes by multivalent ions with an emphasis on its implications for the division and fusion of cells. We fin…
Physical Questions Posed by DNA Condensation
Bae-Yeun Ha, Andrea J. Liu
When multivalent salts are added to dilute DNA solution, the DNA chains condense into bundles of a well-defined size. We explore two physical problems motivated by this phenomenon:…
