The polymer theta-point as a knot delocalisation transition
E. Orlandini, A. L. Stella, C. Vanderzande
We study numerically the tightness of prime flat knots in a model of self-attracting polymers with excluded volume. We find that these knots are localised in the high temperature s…
Inter-strand distance distribution of DNA near melting
M. Baiesi, E. Carlon, Y. Kafri +3
The distance distribution between complementary base pairs of the two strands of a DNA molecule is studied near the melting transition. Scaling arguments are presented for a genera…
A simple model of DNA denaturation and mutually avoiding walks statistics
Marco Baiesi, Enrico Carlon, Enzo Orlandini +1
Recently Garel, Monthus and Orland (Europhys. Lett. v 55, 132 (2001)) considered a model of DNA denaturation in which excluded volume effects within each strand are neglected, whil…
Self-organized random walks and stochastic sandpile: From linear to branched avalanches
S. S. Manna, A. L. Stella
In a model of self-organized criticality unstable sites discharge to just one of their neighbors. For constant discharge ratio and for a certain range of values of the input en…
Topological and geometrical entanglement in a model of circular DNA undergoing denaturation
M. Baiesi, E. Orlandini, A. L. Stella
The linking number (topological entanglement) and the writhe (geometrical entanglement) of a model of circular double stranded DNA undergoing a thermal denaturation transition are…
Scaling in DNA unzipping models: denaturated loops and end-segments as branches of a block copolymer network
Marco Baiesi, Enrico Carlon, Attilio Stella
For a model of DNA denaturation, exponents describing the distributions of denaturated loops and unzipped end-segments are determined by exact enumeration and by Monte Carlo simula…
