Unambiguous knot classification is a long-standing problem. In this paper, the authors use Machine Learning to classify all knots up to 10 crossings with more than 95% accuracy and also to distinguish knots with multiple identical knot polynomials.

Active liquid crystals use topology to create complex structures in curved geometries through mechanical coupling between topological defects and curvature. This links topological defects to morphogenetic events in biological development.

Tracking the three-dimensional rotation of colloidal particles can help to answer many open questions, e.g. concerning the contact interactions between particles under flow, or the way in which obstacles and neighboring particles affect self-propulsion in active suspensions.

Computer simulations reveal the effects of contour length asymmetry, cavity elongation and polymer width on the organization and dynamics of a system of two polymers in a nanocavity.

Precessing magnetic fields will induce positional ordering of superparamagnetic rods solely due to steric collisions. This transition occurs regardless of what induces precession and leads to synchronization-driven phase separation.

We demonstrate how addition of polyvinylpyrrolidone (PVP, a non-adsorbing polymer) affects the rheology of concentrated aqueous suspensions of colloidal alumina particles.

We numerically explore diffusiophoretic banding of colloidal particles in two dimensions by spatio-temporally designing solute sources and sinks. We discover an optimal design set by a balance of interpole diffusion and molar rate decay timescales.

Geometric frustration offers a pathway to soft matter self-assembly with controllable finite sizes. Microscopic features of misfitting particle shapes and interactions dictate the nature of inter-assembly stress of frustrated, hyperbolic ribbons.
