Multidimensional, dual-channel vortex beam generator

Optical vortices, characterized by a helical phase front and doughnut-shaped intensity distribution, contribute to a broad range of applications, from microscopy to optical communications. And applications for optical vortices ...

Researchers discover skyrmions can split like biological cells

Scientists at the U.S. Department of Energy's Ames Laboratory have discovered that skyrmions— a type of quasiparticle with properties that could lead to the next generation of data storage and transfer— reproduce by splitting ...
