They showed that polariton quantum vortices formed in the neighboring cells of optically generated lattices tend to have an opposite topological vortex charge, i.e., the vortices are ...

Innovative study reveals topological valley vortex states in water waves. Science China Press. Journal Science Bulletin DOI 10.1016/j.scib.2025.01.009. Keywords /Physical sciences/ Physics ...

A new laser based on a swirling vortex of light has been created by physicists in the US. The “topological-defect laser” could be a useful addition to lab-on-a-chip devices, where it could manipulate ...

Vortex-antivortex pairs found in magnetic trilayers The discovery in the new fields of topological spintronics and 3-D nanomagnetics could have applications for memory and logic devices ...

Boston College Professor of Physics Ziqiang Wang, postdoctoral fellow Kun Jian, and Hong Kong University of Science and Technology Professor Xi Dai say their calculations reveal that a certain class ...

Researchers have developed a method to emit electromagnetic vortex rings using coaxial horn antennas, similar to an "electromagnetic air cannon." These vortex pulses demonstrate stable propagation ...

Toroidal electromagnetic pulses can be generated using a device known as a horn microwave antenna. This electromagnetic “vortex cannon” produces skyrmion topological structures that might be employed ...

For thirty years, scientists have theorized that it should be possible to create electromagnetic “focused doughnuts” not topologically dissimilar from the vortex rings that form naturally in ...

Researchers posit that these states can be used to construct topological qubits—zones protected from noise and decoherence provoked by local perturbations. These zones are central to a relatively new ...
