We are reaching the limits of silicon capabilities in terms of data storage density and speed of memory devices. One of the potential next-generation data storage elements is the magnetic skyrmion.  Taking electrons out for a spin through the nanoscopic streets of a digital device – without spinning out of control – has challenged researchers for years.  Konstanz physicist Professor Peter Baum and his team have succeeded in spatially and temporally directing and controlling ultrashort electron pulses directly by using the light cycles of laser light instead of microwaves.  In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage.  Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light.  Researchers at the University of Central Florida have generated what is being deemed the fastest light pulse ever developed.  Physicists at Chalmers University of Technology and Free University of Brussels have now found a method to significantly enhance optical force.
