Supercoiling DNA with a free end
Daniela Moretti, Giuseppe Gonnella, Antonio Suma +3
In this work, we combine coarse-grained Brownian dynamics simulations and mean-field theory to study supercoiling dynamics, as well as the steady-state profiles of twist and writhe…
When Knots are Plectonemes
Fei Zheng, Antonio Suma, Christopher Maffeo +6
The transport of DNA polymers through nanoscale pores is central to many biological processes, from bacterial gene exchange to viral infection. In single-molecule nanopore sensing,…
Unzipping of knotted DNA via nanopore translocation
Antonio Suma, Cristian Micheletti
DNA unzipping by nanopore translocation has implications in diverse contexts, from polymer physics to single-molecule manipulation to DNA-enzyme interactions in biological systems.…
Topological jamming of spontaneously knotted polyelectrolyte chains driven through a nanopore
A. Rosa, M. Di Ventra, C. Micheletti
The advent of solid state nanodevices allows for interrogating the physico-chemical properties of a polyelectrolyte chain by electrophoretically driving it through a nanopore. Sali…
Surface spin-flop phases and bulk discommensurations in antiferromagnets
C. Micheletti, R. B. Griffiths, J. M. Yeomans
Phase diagrams as a function of anisotropy D and magnetic field H are obtained for discommensurations and surface states for a model antiferromagnet in which is parallel to the…
Complete wetting in the three-dimensional transverse Ising model
A. B. Harris, C. Micheletti, J. M. Yeomans
We consider a three-dimensional Ising model in a transverse magnetic field, and a bulk field . An interface is introduced by an appropriate choice of boundary conditions. At…
An Upsilon Point in a Spin Model
C. Micheletti, F. Seno, J. M. Yeomans
We present analytic evidence for the occurrence of an upsilon point, an infinite checkerboard structure of modulated phases, in the ground state of a spin model. The structure of t…
