Alexei Alexeyevich Abrikosov Alexei Alexeyevich Abrikosov (Russian: Алексе́й Алексе́евич Абрико́сов ; 25 June 1928 – 29 March 2017) was a Soviet, Russian and American theoretical physicist whose main contributions are in the field of condensed matter physics. He was awarded the Nobel Prize in Physics in 2003.
Yuri Golfand Yuri Abramovich Golfand (Russian: Ю́рий Абра́мович Го́льфанд ; January 10, 1922, in Kharkiv – February 17, 1994, in Jerusalem) was a Russian and Israeli physicist known, in particular, for his 1971 paper (joint with his student Evgeny Likhtman) where they proposed supersymmetry between bosonic and ferminoic particles by extending the Poincaré algebra with anticommuting spinor generators. The algebra they constructed is also called a Super-Poincaré algebra. In the very same paper they presented the ﬁrst four-dimensional supersymmetric
