Extracting short-ranged interactions from structure factors
Ard A. Louis
Inverting scattering experiments to obtain effective interparticle interactions is generally a poorly conditioned problem. L. Reatto (Phil. Mag. A 58, 37 (1986)) showed that for at…
How Peclet number affects microstructure and transient cluster aggregation in sedimenting colloidal suspensions
A. Moncho-Jorda', A. A. Louis, J. T. Padding
We study how varying the P éclet number (Pe) affects the steady state sedimentation of colloidal particles that interact through short-ranged attractions. By employing a hybrid mol…
Confinement of knotted polymers in a slit
R. Matthews, A. A. Louis, J. M. Yeomans
We investigate the effect of knot type on the properties of a ring polymer confined to a slit. For relatively wide slits, the more complex the knot, the more the force exerted by t…
Pattern formation in colloidal explosions
Arthur V. Straube, Ard A. Louis, Jörg Baumgartl +2
We study the non-equilibrium pattern formation that emerges when magnetically repelling colloids, trapped by optical tweezers, are abruptly released, forming colloidal explosions.…
Complex dynamics of knotted filaments in shear flow
R. Matthews, A. A. Louis, J. M. Yeomans
Coarse-grained simulations are used to demonstrate that knotted filaments in shear flow at zero Reynolds number exhibit remarkably rich dynamic behaviour. For stiff filaments that…
Effect of topology on dynamics of knots in polymers under tension
R. Matthews, A. A. Louis, J. M. Yeomans
We use computer simulations to compare the dynamical behaviour of torus and even-twist knots in polymers under tension. The knots diffuse through a mechanism similar to reptation.…
