The spin-dependence of Andreev reflection gives rise to the Point contact Andreev reflection technique, whereby a narrow superconducting tip (often niobium, antimony or lead) is placed into contact with a normal material at temperatures below the critical temperature of the tip. By applying a voltage to the tip, and measuring differential ...
Alexander Fyodorovich Andreev (Russian: Александр Фёдорович Андреев, 10 December 1939 – 14 March 2023) [1] was a Russian theoretical physicist best known for explaining the eponymous Andreev reflection. [2] Andreev was educated at the Moscow Institute of Physics and Technology, starting in 1959 and graduating ahead of ...

The San Diego Padres completed a game-ending triple play, clinched a playoff berth and kept their hopes of winning the NL West alive with their 4-2 defeat of the Los Angeles Dodgers on Tuesday at ...
Score was the weekend sports service of the Financial News Network which aired sports-themed programming starting in 1985. It was renamed FNN Sports in 1989 after FNN decided to go with a 24-hour feed on weekdays a year earlier. Score was closed when CNBC bought out FNN in 1991.
It was also the first triple play the Phillies had turned since 2017 and the first 1-3-5 triple play in Major League Baseball since 1929, according to The Athletic's Jayson Stark. Remarkably, that ...
Diagram of Andreev reflection. An electron meeting the interface between a normal conductor and a superconductor produces a Cooper pair in the superconductor and a retroreflected electron hole in the normal conductor. Legend: "N" = normal conductor, "S" = superconductor, red = electron, green = hole. Arrows indicate the spin band occupied by ...
