• Probability Waves Could Be Used as “Tractor Beams” to Control Nanoobjects

  Tractor beams first became a topic of conversation two centuries ago in science fiction: the term implied a beam of light that could lift and move various objects. It is commonly associated with aliens pulling objects from Earth aboard their flying saucers. An idea that seemed improbable some decades ago has become real: scientists all over the world are coming up with ways of moving objects. Although, for now, these “tractor beams” can only move nanoparticles. An international research group that includes a scientist from ITMO University has contributed to this field of study: they have proven that de Broglie waves (probability waves), which in quantum mechanics denote a matter wave, are also capable of displaying the properties of a tractor beam.

• Trapping Light: Anisotropic Structures Can Increase Optical Device's Efficiency

  ITMO's scientists Yuri Kivshar and Mikhail Rybin published an article in the News&Views section of the Nature Photonics journal on the research of their colleagues from Barcelona Institute of Science and Technology. The article explains how the Spanish researchers succeeded in using the anisotropic properties of a compound for creating simpler yet more effective optical devices based on the so-called bound states in continuous spectrum. In future, this discovery can be applied in optical detection systems and other devices, shared Mikhail Rybin, Deputy Head of ITMO's Department of Dielectric and Semiconductor Photonics and senior research officer of the Spectroscopy of Solids Laboratory of the Ioffe Institute.

• New Material Makes it Possible to Record Data with Light

  Russian physicists with their colleagues from Europe through changing the light parameters, learned to generate quasiparticles — excitons, which were fully controllable and also helped to record information at room temperature. These particles act as a transitional form between photons and electrons so the researchers believe that with excitons, they will be able to create compact optoelectronic devices for rapid recording and processing an optical signal. The proposed method is based on the use of a special class of materials called metal-organic frameworks. The study appeared in Advanced Materials.

• Interactive Microscopy for Children by ITMO University

  Specialists of NT-SPB, one of ITMO Technopark’s residents, developed an equipment system for interactive classes on physics. Some 18 high-schools of St. Petersburg have already installed the system in their classes where children will take the first steps towards science.

• The "Dream Tasks" of Photonics: Sergei Makarov and Anvar Zakhidov Share about ITMO’s Collaboration on Hybrid Perovskites

  In the end of last September, ITMO University and the University of Texas at Dallas won a big grant, which will be used to build Russia's first laboratory for creating new optoelectric devices based on hybrid perovskites. So, how will the unique laboratory work, what are flexible lasers and is it possible to create a teraherz device that can see trough walls? Learn this and more from our article.
