The elasticity of semiflexible polymers with reversible spontaneous curvature in two dimensions
Donghyeon Kim, Panayotis Benetatos
Many semiflexible filaments exhibit structural asymmetries that lead to a curved ground state (curvature in the absence of thermal fluctuations, external forces, or torques). This…
Cross-linked pair of polymer chains under strong tension
Geunho Noh, Panayotis Benetatos
We study two cross-linked polymer systems in the strong stretching regime. The first consists of two polymers sharing one endpoint, with the other two endpoints coupled by a harmon…
Elasticity of a Freely Jointed Chain with Quenched Disorder
Minsu Yi, Panayotis Benetatos
We introduce a simple theoretical model, the Freely Jointed Chain with quenched hinges (qFJC), which captures the quenched disorder in the local bending stiffness of the polymer. I…
Bending Elasticity of the reversible Freely Jointed Chain
Minsu Yi, Dongju Lee, Panayotis Benetatos
The freely jointed chain model with reversible hinges (rFJC) is the simplest theoretical model that captures reversible transitions of the local bending stiffness along the polymer…
Inequivalence of fixed-force and fixed-extension statistical ensembles for a flexible polymer tethered to a planar substrate
Sandipan Dutta, Panayotis Benetatos
Recent advances in single macromolecule experiments have sparked interest in the ensemble dependence of force-extension relations. The thermodynamic limit may not be attainable for…
Tensile elasticity of semiflexible polymers with hinge defects
Panayotis Benetatos
It has become clear in recent years that the simple uniform wormlike chain model needs to be modified in order to account for more complex behavior which has been observed experime…
