The probability distribution of the average relative distance between two points in a dynamical chain
Franco Ferrari, Jaroslaw Paturej, Thomas A. Vilgis +1
Subject of this letter is the dynamics of a chain obtained performing the continuous limit of a system of links and beads. In particular, the probability distribution of the relati…
Applications of a generalization of the nonlinear sigma model with O(d) group of symmetry to the dynamics of a constrained chain
Franco Ferrari, Jaroslaw Paturej, T. A. Vilgis
Subject of this work are the applications of a field theoretical model, called here generalized nonlinear sigma model or simply GNLSM,to the dynamics of a chain subjected to constr…
Adsorption of Multi-block and Random Copolymer on a Solid Surface: Critical Behavior and Phase Diagram
Swati Bhattacharya, Hsiao-Ping Hsu, Andrey Milchev +2
The adsorption of a single multi-block -copolymer on a solid planar substrate is investigated by means of computer simulations and scaling analysis. It is shown that the proble…
Polyelectrolyte gels in poor solvent: Equilibrium and non equilibrium elasticity
T. A. Vilgis, A. Johner, J. -F. Joanny
We study theoretically using scaling arguments the behavior of polyelectrolyte gels in poor solvents. Following the classical picture of Katchalsky, our approach is based on single…
Stretching necklaces
T. A. Vilgis, A. Johner, J. -F. Joanny
Polyelectrolytes in poor solvents show a necklace structure where collapsed polymer pearls are linked to stretched strings. In the present paper the elasticity of such chains is st…
Crosslinked polymer chains with excluded volume: A new class of branched polymers?
T. A. Vilgis
In this note microgels with and without excluded volume interactions are considered. Based on earlier exact computations on Gaussian mircogels, which are formed by self-crosslinkin…
