Annealed lattice animal model and Flory theory for the melt of non-concatenated rings: Towards the physics of crumpling
Alexander Y. Grosberg
A Flory theory is constructed for a long polymer ring in a melt of unknotted and non-concatenated rings. The theory assumes that the ring forms an effective annealed branched objec…
From a melt of rings to chromosome territories: The role of topological constraints in genome folding
Jonathan D. Halverson, Jan Smrek, Kurt Kremer +1
We review pro and contra of the hypothesis that generic polymer properties of topological constraints are behind many aspects of chromatin folding in eukaryotic cells. For that pur…
Electrophoretic Capture of a DNA Chain into a Nanopore
Payam Rowghanian, Alexander Y. Grosberg
Based on our formulation of the DNA electrophoresis near a pore [P. Rowghanian and A. Y. Grosberg, Phys. Rev. E 87, 042723 (2013)], we address the electrophoretic DNA capture into…
Electrophoresis of a DNA Coil Near a Nanopore
Payam Rowghanian, Alexander Y. Grosberg
Motivated by DNA electrophoresis near a nanopore, we consider the flow field around an "elongated jet", a long thin source which injects momentum into a liquid. This solution quali…
Propagation of Tension along a Polymer Chain
Payam Rowghanian, Alexander Y. Grosberg
We study the propagation of tension caused by an external force along a long polymeric molecule in two different settings, namely along a free polymer in 3d space being pulled from…
Exact expressions for the mobility and electrophoretic mobility of a weakly charged sphere in a simple electrolyte
Ludvig Lizana, Alexander Y. Grosberg
We present (asymptotically) exact expressions for the mobility and electrophoretic mobility of a weakly charged spherical particle in an electrolyte solution. This is done by…
