• The New Kilogram: Reasons Behind Upcoming Measurement Reform

  Held in Versailles, the 26th General Conference on Weights and Measures was the site of a historic decision to redefine the kilogram. Simply put, it is now immaterial and will be defined via a formula and not, as it had been before, via a material artifact. The effect of that change is that we can now reproduce the perfect kilogram anywhere on Earth without using conventional measurement devices or making comparisons to a standard physical prototype.

• Scientists Propose a Fully Optical Method for Near-Field Reshaping and Enhancement in Hybrid Metal-Dielectric Oligomers

  Scientists from ITMO University in collaboration with researchers from Saint Petersburg Academic University have developed a fully optical method that allows to reconfigure the properties of hybrid metal-dielectric oligomers in the near field. This offers a simpler and cheaper alternative to the existing methods of working with such structures. The use of metal-dielectric oligomers has a lot of potential for developing new data recording devices, as well as in sensor science. The research was published in Laser & Photonics Reviews.

• Scientists Create First Topological Nanostructures Which Make Infrared Light Visible

  An international group of physicists has developed a topological nanostructure that converts infrared radiation into green light. It is represented by zigzag arrays of silicon nanodisks with diameters of 500 nanometers placed on a glass substrate. The results have been published in Nature Nanotechnology.

• Tel Aviv University Professor Boris Malomed on Non-Linear Physics and Solitons

  The field of optics has the potential to radically change the way we use information. During a visit to ITMO University, Professor Boris Malomed from the Tel Aviv University shared some insights into his work. Prof. Malomed has spent more than 30 years in the field of non-linear optics and solitons. His h-index is among the highest of all researchers in this subject area. In an interview for ITMO.NEWS, Boris Malomed explained how optics shape our lives today and what effects it has on other fields of physics.

• ITMO Students Take First Place in Physics Competition

  For the first time ever, ITMO University students won the annual regional student competition in physics. Denis Sedov and Anton Shubnik, second-year Bachelor’s students at the Faculty of Physics and Engineering, took first place in both team and individual championships. The competition was held at St. Petersburg Electrotechnical University “LETI”. In this interview with ITMO.NEWS, the winners share their advice on how to solve competitions tasks to succeed.

• Study Reveals The Great Pyramid of Giza Can Focus Electromagnetic Energy

  An international research group applied methods of theoretical physics to study the electromagnetic response of the Great Pyramid to radio waves. Scientists found out that under resonance conditions the pyramid can concentrate electromagnetic energy both in its internal chambers and the area located under its base. The research group plans to apply these findings to design nanoparticles capable of reproducing similar effects in the optical range. Such nanoparticles may be used to develop sensors and highly efficient solar cells. The study was published in the Journal of Applied Physics.

• Track the Growth of Scoliosis using Mathematical Models

  Musculoskeletal system diseases do not only worsen the quality of life but they can also lead to other diseases, including cardiovascular ones. Scoliosis is one of the most common musculoskeletal system diseases. Researchers from ITMO’s Department of Nano-Photonics and Metamaterials and Department of Advanced Mathematics together with the Ogonek Pediatric Orthopedics and Traumatology Center (Strelna), headed by Mikhail Dudin, are working on a physical and mathematical model of scoliosis that will help doctors more accurately diagnose the disease.

• What to Expect from a Master’s Program at the Faculty of Physics and Engineering

  This year, the Faculty of Physics and Engineering at ITMO University is accepting applications for its Master’s degree programs “Radiofrequency Systems and Devices” and “Nanophotonics and Metamaterials” which were launched the previous year. We spoke to students who enrolled last year to find out what to expect from Master’s studies at the faculty and what research students get to take part in.

• Physicist Yuri Kivshar on Russian Science, Career Management and Metaoptics

  Seven years ago, ITMO University launched the Metamaterials Laboratory. It all began with a grant won by Yuri Kivshar, a world-class scientist and one of Russia’s top physicists. Since then, the university has also launched the Department, and later, the International Research Center of Nanophotonics and Metamaterials. Under Yuri Kivshar’s leadership, the center’s researchers were the first in the world to venture into a completely new field: dielectric nanophotonics, or, as the scientist calls it, “metaoptics”. ITMO.NEWS met with Yuri Kivshar during his latest visit to St. Petersburg to discuss his current work, the future of the most unorthodox field of nanophotonics, and why a scientist shouldn’t stick with the same field of study for their entire life.
