The International Day of Light is celebrated annually on May 16. It is dedicated to the role of light in life, science, art, culture and other spheres. The Institute of Spectroscopy of the Russian Academy of Sciences published the news about this event on its website. So, we had the idea to hold a Day of Light event for students and applicants of the Faculty of Physics. The academic curators of the faculty supported and developed the idea. We decided to tell junior students and schoolchildren about the world of science in simple language. Senior students got an opportunity to make presentations of their research papers.

After registering and meeting near the hall of HSE University building on Basmannaya Ulitsa, the event participants (including students, applicants and guests of the faculty), attended lectures and presentations of interesting scientific reports.

Igor Baliukin, Associate Professor at the Joint Department of Space Physics with the Space Research Institute (RAS), spoke about the heliosphere model, the propagation of light in the galaxy, the mission of the two Voyager spacecraft, and prospects and new hypotheses.

Kirill Boldyrev, senior researcher at the Fourier Transform Spectroscopy Laboratory of the Institute of Spectroscopy of the Russian Academy of Sciences, impressed students and guests with experiments with light, multicoloured diamonds and lenses, ultraviolet radiation and low temperatures, and demonstrated the wave theory of light on the ceiling of the lecture hall.

Konstantin Eltsov, Professor at the Joint Department of Quantum Technologies with Prokhorov General Physics Institute (RAS), recalled that science is rapidly moving forward and that things that recently seemed unreal have already become part of our everyday life. New discoveries in the field of quantum technologies are yet to come, including the creation of a quantum computer.

In the second part of the programme, master's and bachelor's students presented their reports on such topics as light, quantum technologies, and more.

Polina Vinetskaya, master’s student of the Joint Department of Quantum Technologies with Prokhorov General Physics Institute (RAS), spoke about classical cryptography, ciphers, spies and quantum money. Arina Safonova, fourth-year bachelor’s student, connected physics and biology in her study of optical methods of DNA sequencing. Guests of the event learned about the new, eternal and fleeting from a report by first-year master’s student Daria Bykova, who studies laser cooling of atoms and atomic clocks.

We invited third- and fourth-year students who wished to share their projects to take part in poster sessions aimed at illustrating the various applications of light in science. It was their first experience and an opportunity to present the results of their research almost at a professional level in a conference format.

The day ended with a tour of the laboratory workshops of the Faculty of Physics conducted by junior students. Guests had an opportunity to see where undergraduates experimentally study physical phenomena from various branches of physics, from mechanics to optics.

Russian Scientists Pioneer Accurate Mathematical Description of Quantum Dicke Battery

Physicists at HSE University and NUST MISIS have formulated and solved equations for a quantum battery, a device capable of storing energy in the form of light. Their findings will facilitate precise calculations of the capacity, power, and duration required for optimal battery charging. Quantum batteries are expected to improve the performance of solar panels and electric vehicles, while also opening up new avenues for efficient energy transfer. The study has been published in Physical Review A.

Scientists Harness 'Liquid Light' to Induce Electric Current in Superconductors

Scientists at HSE MIEM have induced a superconducting current using 'liquid light,' or excitonic polaritons, which are hybrid particles formed by interaction between light and matter and possess the properties of both light and material particles. The ability to manipulate an electrical system through an optical one can be valuable in the development of technologies such as quantum computers. The study has been published in Physical Review B.

This year, on February 13–17, the tournament will be held at HSE University for the first time. It will include two rounds—the qualifiers and the final. In the final round, three teams and their captains will compete with each other.

Lavsan and Kapton Tested Under Space-like Radiation Conditions

In a ground-breaking experiment, HSE MIEM researchers subjected Lavsan (polyethylene terepfthalate, polyester) and Kapton (polypiromellitimide, polyimide) polymers, commonly used in space technology, to ionising radiation for durations ranging from microseconds to several hours at temperatures of -170°C and +20°C, while comparing their electrical conductivity under extreme conditions. The study reveals that at -170°C, Kapton's conductivity is ten times lower than at +20°C. These findings can assist engineers in developing more effective protection for spacecraft against static discharges induced by ionising radiation. The study has been published in Journal of Applied Physics.

Human Bodies Impede 6G Signal Transmission

A team of researchers, including scientists from HSE University, have investigated the influence of human movement on the propagation of 6G signals. Within a range of up to 10 metres, the signal attenuation is comparatively minor, yet brief connection failures may still occur. Based on the study findings, a blockage detection algorithm has been developed to account for both signal attenuation and interruptions. The gaming industry is likely to derive the greatest benefits from this discovery. A paper with the study findings has been published in Computer Communications.
