Abstract

The article is dedicated to memories of Dr.Sc. Yaroslav Georgievich Ponomarev (1938–2015), Professor of the Low Temperature Physics and Superconductivity Deparment, Faculty of Physics, Lomonosov Moscow State University, the head of the laboratory of tunneling spectroscopy of superconductors. The authors tried to characterize him from different sides, as a person and as a scientist. The history of the Leggett plasma mode discovery in 2002 made by Professor Ya.G. Ponomarev in the first known two-gap superconductor, magnesium diboride, is given.

Keywords: high-temperature superconductivity; multigap superconductors, MgB2; Josephson spectroscopy; Andreev spectroscopy; Leggett plasma mode.
