Alexander Yefimov
Aleksandr Nikolaevich Yefimov (russian: Александр Николаевич Ефимов; 6 February 1923 – 31 August 2012) was a senior military officer who served as Commander-in-Chief of the Soviet Air Force from 1984 to 1990. Earlier in his life, he had been an Il-2 pilot for which he was twice awarded the title Hero of the Soviet Union. Early life Yefimov was born on 6 February 1923 to a working-class family of Russian Don Cossacks in Kantemirovka; his father was a railway worker. He spent most of his childhood in Millerovo, where he completed his tenth grade of school in 1940. There he developed a passion for aviation, joining the local Osoaviakhim glider school, where he made his first flight on 18 August 1938. He then went on to graduate from the Voroshilovgrad aeroclub in May 1941 and entered the military that month. After graduating from the Voroshilovgrad Military Aviation School of Pilots in June 1942 he was assigned as a pilot to the 10th Reserve Aviation Regi ...

Hero Of The Soviet Union
The title Hero of the Soviet Union (russian: Герой Советского Союза, translit=Geroy Sovietskogo Soyuza) was the highest distinction in the Soviet Union, awarded together with the Order of Lenin personally or collectively for heroic feats in service to the Soviet state and society. Overview The award was established on 16 April 1934, by the Central Executive Committee of the Soviet Union. The first recipients of the title originally received only the Order of Lenin, the highest Soviet award, along with a certificate (грамота, ''gramota'') describing the heroic deed from the Presidium of the Supreme Soviet of the USSR. Because the Order of Lenin could be awarded for deeds not qualifying for the title of hero, and to distinguish heroes from other Order of Lenin holders, the Gold Star medal was introduced on 1 August 1939. Earlier heroes were retroactively eligible for these items. A hero could be awarded the title again for a subsequent heroic feat with ...

Mikhail Efimov
2754 Efimov, provisionally named , is a stony asteroid and binary system from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 13 August 1966, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula. The asteroid was named after Russian aviator Mikhail Efimov. Orbit and classification ''Efimov'' orbits the Sun in the inner main-belt at a distance of 1.7–2.7 AU once every 3 years and 4 months (1,214 days). Its orbit has an eccentricity of 0.23 and an inclination of 6 ° with respect to the ecliptic. Physical characteristics In the SMASS classification, ''Efimov'' is a Sa-type asteroid, which belong to the larger group of S-type asteroids. It is also characterized as a L-type asteroid by PanSTARRS photometric survey. The ''Collaborative Asteroid Lightcurve Link'' assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 4.98 kilometers ...

Vitaly Efimov
Vitaly N. Efimov (Russian: Вита́лий Никола́евич Ефи́мов) is a Russian theoretical physicist. He proposed the existence of a novel and exotic state of matter now dubbed the Efimov State as a researcher in A. F. Ioffe Physico-Technical Institute, USSR Academy of Sciences, Leningrad, USSR in his 1970 paper "Energy levels arising from resonant two-body forces in a three-body system". It was announced in 2006 that the existence of this state of matter had been confirmed. He is now an affiliate professor of physics at the University of Washington The University of Washington (UW, simply Washington, or informally U-Dub) is a public research university in Seattle, Washington.

Efimov State
The Efimov effect is an effect in the quantum mechanics of few-body systems predicted by the Russian theoretical physicist V. N. Efimov in 1970. Efimov’s effect is where three identical bosons interact, with the prediction of an infinite series of excited three-body energy levels when a two-body state is exactly at the dissociation threshold. One corollary is that there exist bound states (called Efimov states) of three bosons even if the two-particle attraction is too weak to allow two bosons to form a pair. A (three-particle) Efimov state, where the (two-body) sub-systems are unbound, is often depicted symbolically by the Borromean rings. This means that if one of the particles is removed, the remaining two fall apart. In this case, the Efimov state is also called a Borromean state. Theory Efimov predicted that, as the pair interactions among three identical bosons approach resonance—that is, as the binding energy of some two-body bound state approaches zero or the scatteri ...
