• ITMO Physicists Twist Electrons for Particle Accelerator Experiments

  Researchers from ITMO University are the first to have found a way to twist electrons with a laser beam, opening up a path towards experiments with twisted electrons in particle colliders – a feat previously considered impossible. The discovery will make it possible to learn more about the structure and behavior of protons and neutrons that make up atom nuclei, as well as look into the nature of quarks, some of the smallest known matter particles. The results of the study are described in a paper published in Physical Review A.

• ITMO Researchers Explore Direct Laser Writing of Nanolattices

  Researchers from ITMO’s Faculty of Nanoelectronics together with their colleagues from the Lebedev Physical Institute, D. Mendeleev University of Chemical Technology of Russia, and the National Research Nuclear University MEPhI have conducted a study that showed that nanolattices possess high spectral selectivity. Their layers can be used as color filters for specific wavelength ranges, and one glass plate can contain records of up to six layers. Using this technology, the scientists were able to implement dispersive birefringent filters, which have multiple applications. For instance, they can be used to create AR/VR color displays or novel biochemical sensors for bacterial analysis.

• Researchers Find Way to Enhance Photon Entanglement

  Scientists from ITMO University figured out how to design more efficient and compact devices for generating pairs of entangled photons. The research team found that the number of entangled photons increased when the light beam passed through a special nanolattice compiled of metal layers. The effect of entanglement is enhanced by a strong electrical field arising in the lattice. Previously, such experiments could not be analyzed theoretically, which is why the new method opens big opportunities in designing a wide range of quantum devices, for example, elements of optical computers and secure communication systems. The results were published in Physical Review Letters.
