Bubble merging in breathing DNA as a vicious walker problem in opposite potentials
Jonas Nyvold Pedersen, Mikael Sonne Hansen, Tomas Novotny +2
We investigate the coalescence of two DNA-bubbles initially located at weak domains and separated by a more stable barrier region in a designed construct of double-stranded DNA. In…
Diffusion of two particles with a finite interaction potential in one dimension
Tobias Ambjornsson, Robert J. Silbey
We investigate the dynamics of two interacting diffusing particles in an infinite effectively one dimensional system; the particles interact through a step-like potential of width…
Single-file dynamics with different diffusion constants
Tobias Ambjornsson, Ludvig Lizana, Michael A. Lomholt +1
We investigate the single-file dynamics of a tagged particle in a system consisting of N hardcore interacting particles (the particles cannot pass each other) which are diffusing i…
Breathing dynamics in heteropolymer DNA
Tobias Ambjornsson, Suman K. Banik, Oleg Krichevsky +1
While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation…
Applying a potential across a biomembrane: electrostatic contribution to the bending rigidity and membrane instability
Tobias Ambjornsson, Michael A. Lomholt, Per Lyngs Hansen
We investigate the effect on biomembrane mechanical properties due to the presence an external potential for a non-conductive non-compressible membrane surrounded by different elec…
Sequence sensitivity of breathing dynamics in heteropolymer DNA
Tobias Ambjornsson, Suman K. Banik, Oleg Krichevsky +1
We study the fluctuation dynamics of localized denaturation bubbles in heteropolymer DNA with a master equation and complementary stochastic simulation based on novel DNA stability…
