Nucleosome Switching
David J. Schwab, Robijn F. Bruinsma, Joseph Rudnick +1
We present a statistical-mechanical analysis of the positioning of nucleosomes along one of the chromosomes of yeast DNA as a function of the strength of the binding potential and…
Thermodynamic restrictions on evolutionary optimization of transcription factor proteins
Longhua Hu, Alexander Y. Grosberg, Robijn Bruinsma
Conformational fluctuations are believed to play an important role in the process by which transcription factor proteins locate and bind their target site on the genome of a bacter…
Chirality and Equilibrium Biopolymer Bundles
Gregory M. Grason, Robijn F. Bruinsma
We use continuum theory to show that chirality is a key thermodynamic control parameter for the aggregation of biopolymers: chirality produces a stable disperse phase of hexagonal…
Phase Diagram of Chiral Biopolymer Wigner Crystals
Gregory M. Grason, Robijn F. Bruinsma
We study the statistical mechanics of counterion Wigner crystals associated with hexagonal bundles of chiral biopolymers. We show that, due to spontaneous chiral symmetry breaking…
Frustrated Polyelectrolyte Bundles and T=0 Josephson-Junction Arrays
Gregory M. Grason, Robijn F. Bruinsma
We establish a one-to-one mapping between a model for hexagonal polyelectrolyte bundles and a model for two-dimensional, frustrated Josephson-junction arrays. We find that the T=0…
Soft elasticity of RNA gels and negative Poisson ratio
Amir Ahsan, Joseph Rudnick, Robijn Bruinsma
We propose a model for the elastic properties of RNA gels. The model predicts anomalous elastic properties in the form of a negative Poisson ratio and shape instabilities. The anom…
