Statistics of confined polymers and the melting of a DNA spool

Research output: Contribution to journalArticlepeer-review

Abstract / Description of output

Using Monte Carlo simulations, we analyse the statistical properties of a semiflexible polymer strongly confined in space into an ellipsoidal hull. We show evidence of a sharp crossover or of a phase transition, between ordered structures such as spools, and disordered ones, as a function of the persistence length of the chain. We discuss our results in relation to the packing of double-stranded DNA molecules inside bacteriophage capsids, a biological system which our results suggest is positioned close to the crossover/transition point.
