Dynamics of a stiff biopolymer in an actively contractile background: buckling, stiffening and negative dissipation
Norio Kikuchi, Allen Ehrlicher, Daniel Koch +3
We present a generic theory for the dynamics of a stiff filament under tension, in an active medium with orientational correlations, such as a microtubule in contractile actin. In…
DNA toroid condensation as analytic solutions
Yukitaka Ishimoto, Norio Kikuchi
It now becomes apparent that condensed DNA toroid which emerges in a poor solvent condition can be realised in the framework of the non-linear sigma model on a line segment. In fac…
Analytic theory of DNA condensation
Yukitaka Ishimoto, Norio Kikuchi
We introduce a novel model for DNA condensation (whip-toroid transition) using the path integral method in the framework of the non-linear sigma model on a line segment. We show th…
Transport coefficients of a mesoscopic fluid dynamics model
N. Kikuchi, C. M. Pooley, J. F. Ryder +1
We investigate the properties of stochastic rotation dynamics (Malevanets-Kapral method), a mesoscopic model used for simulating fluctuating hydrodynamics. Analytical results are g…
Polymer collapse in the presence of hydrodynamic interactions
N. Kikuchi, A. Gent, J. M. Yeomans
We investigate numerically the dynamical behaviour of a polymer chain collapsing in a dilute solution. The rate of collapse is measured with and without the presence of hydrodynami…
