Complete Phase Diagram of DNA Unzipping: Eye, Y-fork and triple point
arXiv:cond-mat/0403752 · doi:10.1103/PhysRevLett.93.248102
Abstract
We study the unzipping of double stranded DNA (dsDNA) by applying a pulling force at a fraction from the anchored end. From exact analytical and numerical results, the complete phase diagram is presented. The phase diagram shows a strong ensemble dependence for various values of . In addition, we show the existence of an ``eye'' phase and a triple point.
