Elastic properties of polycatenane chains and ribbons
James M. Polson, Liam MacNevin, Alaaddin Elobeid +1
Single-chain elasticity is of fundamental importance in polymer physics, as it underlies many of the unique properties of polymer systems. Recently, there has been interest in char…
Free-energy landscape of a polymer in the presence of two nanofluidic entropic traps
James M. Polson, Matthew Kozma
Recently, nanofluidics experiments have been used to characterize the behavior of single DNA molecules confined to narrow slits etched with arrays of nanopits. Analysis of the expe…
Flatness and Intrinsic Curvature of Linked-Ring Membranes
James M. Polson, Edgar J. Garcia, Alexander R. Klotz
Recent experiments have elucidated the physical properties of kinetoplasts, which are chain-mail-like structures found in the mitochondria of trypanosome parasites formed from cate…
Equilibrium organization, conformation, and dynamics of two polymers under box-like confinement
James M. Polson, Desiree A. Rehel
Motivated by recent nanofluidics experiments, we use Brownian dynamics and Monte Carlo simulations to study the conformation, organization and dynamics of two polymer chains confin…
Polymer translocation into cavities: Effects of confinement geometry, crowding and bending rigidity on the free energy
James M. Polson, David R. Heckbert
Monte Carlo simulations are used to study the translocation of a polymer into a cavity. Modeling the polymer as a hard-sphere chain with a length up to N=601 monomers, we use a mul…
Free energy and segregation dynamics of two channel-confined polymers of different length
James M. Polson, Qinxin Zhu
Polymers confined to a narrow channel are subject to strong entropic forces that tend to drive the molecules apart. In this study, we use Monte Carlo computer simulations to study…
