Researchers formed stable vortex knots in chiral nematic liquid crystals and used electric pulses to reversibly fuse and split them into different knotted forms. (Nanowerk News) The knots in your ...

The multicore fiber (MCF) is a physical system of high practical importance. In addition to standard exploitation, MCFs may support discrete vortices that carry orbital angular momentum suitable for ...

This paper describes a series of ongoing experiments to capture the details of perpendicular vortex-airfoil interaction. Three test cases explored are: 1) a 21% thick symmetric airfoil at 1.1° angle ...

The Vortex Particle Method (VPM), a meshless vortex flow simulation approach, is gaining traction for its efficient simulation of unsteady vortex wakes evolution that is shed by aircrafts, rotors and ...

Stabilising curve: The arrows show the remnant magnetisation of a toroidal nanomagnet. On the outer edge (the right) we can see a vortex where the magnetisation spirals inwards to a point. An ...

An edge length of a mere thousandth of a millimetre and a thickness of a few millionths of a millimetre: these are the tiny dimensions of the platelets which the researchers in Hermann Stoll’s group ...
