The physicist has already been invited to present and explain his approach in scientific conferences, which reflects the interest shown by the community.  Collisions between neutron stars are fascinating cosmic events that lead to the formation of numerous chemical elements.  Physicists from ITMO University have developed a model of an optical tractor beam to capture particles based on new artificial materials.  Researchers from the Structured Light group from the School of Physics at the University of the Witwatersrand in Johannesburg, South Africa, have found a way to use the full beam of a laser single cells in a human body, tiny particles in small volume chemistry, or working on future on-chip devices.  This research work by the UEx, which has been published in Scientific Reports, explored the electromagnetic properties of specific materials that can make certain objects invisible when they are introduced into its interior.  A research team from ITMO University and the Australian National University has discovered that different metasurfaces exhibit the same behavior provided a symmetry breaking is introduced to their unit cells "meta-atoms." Electron microscopy has allowed scientists to see individual atoms, but even at that resolution not everything is clear.  A half-century ago, the theorist Walter Henneberger wondered if it were possible to use a laser field to free an electron from its atom without removing it from the nucleus.  A new study by researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) may explain this disparity. In the work, the OIST researchers measured electrical current across a two-dimensional plane.  Femtosecond lasers are capable of processing any solid material with high quality and high precision using their ultrafast and ultra-intense characteristics.  To create the flying microlaser, the researchers launched laser light into a water-filled hollow core fiber to optically trap the microparticle. Like the materials used to make traditional lasers, the microparticle incorporates a gain medium.
