Egor Sedov initially planned to pursue a career in programming but instead became captivated by experimental physics. In this interview with the HSE Young Scientists project, he spoke about the quantum effect and the quantum standard, a scientist's letter from the future, and the magnetic levitation of a frog.

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.

Physicists from HSE MIEM in collaboration with colleagues from MIPT and other universities have formulated a theory capable of explaining the transition between different superconductivity types, revealing an intertype regime characterised by exotic magnetic properties. This discovery can serve as the foundation for the development of sensors with enhanced sensitivity and accuracy, capable of functioning in conditions where traditional sensors are less effective. The study has been published in Communications Physics.

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.

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.

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.
