World's first video recording of a space-time crystal

Short and fascinating video! Don't get addicted watching it! :-)

"A team of researchers has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of an ultra-precise X-ray microscope, they were able to capture the recurring periodic magnetization structure in a movie. ..."

"The concept of space-time crystals (STC), i.e., translational symmetry breaking in time and space, was recently proposed and experimentally demonstrated for quantum systems. Here, we transfer this concept to magnons and experimentally demonstrate a driven STC at room temperature. The STC is realized by strong homogeneous microwave pumping of a micron-sized permalloy (Py) stripe and is directly imaged by scanning transmission x-ray microscopy (STXM). ..."
