Robustness against disorder in topological fibre lasers with explicitly broken PT symmetry
Brook Salter, Nathan Roberts, Habib Rostami +2
Fibre lasers realise a large gain medium in a compactly coiled fibre. Disorder due to fabrication can negatively impact the stability of their lasing modes, especially in multi-cor…
More is less in unpercolated active solids
Jack Binysh, Guido Baardink, Jonas Veenstra +2
A remarkable feat of active matter physics is that systems as diverse as collections of self-propelled particles, nematics mixed with molecular motors, and interacting robots can a…
Nonreciprocal buckling makes active filaments polyfunctional
Sami C. Al-Izzi, Yao Du, Jonas Veenstra +5
Active filaments are a workhorse for propulsion and actuation across biology, soft robotics and mechanical metamaterials. However, artificial active rods suffer from limited robust…
Geometry of the vapor layer under a Leidenfrost hydrogel sphere
Vicente L. Diaz-Melian, Isaac C. D. Lenton, Jack Binysh +2
A floating Leidenfrost droplet exhibits curvature inversion of its underside, due to the balance of vapor pressure and surface tension. Using interferometric imaging, we find diffe…
Wave coarsening drives time crystallization in active solids
Jonas Veenstra, Jack Binysh, Vito Seinen +6
When metals are magnetized, emulsions phase separate, or galaxies cluster, domain walls and patterns form and irremediably coarsen over time. Such coarsening is universally driven…
Bouncing microdroplets on hydrophobic surfaces
Jamie Mclauchlan, Jim S. Walker, Vatsal Sanjay +4
Intuitively, slow droplets stick to a surface and faster droplets splash or bounce. However, recent work suggests that on non-wetting surfaces, whether microdroplets stick or bounc…
