Way Dynamic

Researchers report a technique for controlling electrons using three-dimensional structured light fields, a development in ultrafast physics and light-matter interaction. The work suggests new ways to steer electron dynamics with shaped laser beams, with potential implications for attosecond science and quantum control experiments.

The American Physical Society is highlighting work on quasicrystalline water waves, in which fluid surface waves are arranged in quasi-periodic patterns analogous to the atomic structures of quasicrystals. The demonstration extends quasicrystal physics from solid materials into fluid dynamics, offering a new way to study wave interference and symmetry in liquids.
