• ITMO Scientists First to Describe Full Photon Lifecycle in Time and Space

  Physicists from ITMO’s Faculty of Physics have developed a spatial phase method to describe not only the characteristics of an already formed photon, but also the formation of its field in both time and space. Using the Wigner function, the researchers investigated Vavilov-Cherenkov radiation and demonstrated that its spatial structure can retain information about the quantum state of the electron that generated it. The results of the study are published in Physical Review A.

• A New Russian Approach Simplifies Parameter Determination for Twisted Particles in Accelerators

  A group of researchers from ITMO University and the Joint Institute for Nuclear Research have proposed a theoretical method to determine the degree of twist and its direction in electron and ion beams. The new approach offers a more efficient means of studying the parameters of high-energy particles in modern accelerators and can be beneficial for the fields of electron and ion microscopy that use vortex beams. The study is supported by the Russian Science Foundation and is published in Physical Review A.
