In physics, the Bardeen–Cooper–Schrieffer (BCS) theory (named after John Bardeen, Leon Cooper, and John Robert Schrieffer) is the first microscopic theory of superconductivity since Heike Kamerlingh Onnes's 1911 discovery. The theory describes superconductivity as a microscopic effect caused by a condensation of Cooper pairs.
Bogoliubov transformation. In theoretical physics, the Bogoliubov transformation, also known as the Bogoliubov–Valatin transformation, was independently developed in 1958 by Nikolay Bogolyubov and John George Valatin for finding solutions of BCS theory in a homogeneous system. [1][2] The Bogoliubov transformation is an isomorphism of either ...
The Cooper pair state is responsible for superconductivity, as described in the BCS theory developed by John Bardeen, Leon Cooper, and John Schrieffer for which they shared the 1972 Nobel Prize. [2] Although Cooper pairing is a quantum effect, the reason for the pairing can be seen from a simplified classical explanation.
The complete microscopic theory of superconductivity was finally proposed in 1957 by John Bardeen, Leon N. Cooper, and Robert Schrieffer. This BCS theory explained the superconducting current as a superfluid of Cooper pairs, pairs of electrons interacting through the exchange of phonons. For this work, the authors were awarded the Nobel Prize ...
Physics. Institutions. Brown University. Doctoral advisor. Robert Serber. Leon N. Cooper[1] (born February 28, 1930) is an American physicist and Nobel Prize laureate who, with John Bardeen and John Robert Schrieffer, developed the BCS theory of superconductivity. [2][3] His name is also associated with the Cooper pair and the BCM theory of ...
Pages. 588. ISBN. 978-981-4304-64-1. BCS: 50 Years is a review volume on the topic of superconductivity edited by Leon Cooper, a 1972 Nobel Laureate in Physics, and Dmitri Feldman of Brown University, first published in 2010. [1] The book consists of 23 articles written by outstanding physicists, including many Nobel prize-winners, and presents ...
The theory of superconductivity (1964) Doctoral advisor. John Bardeen. John Robert Schrieffer (/ ˈʃriːfər /; May 31, 1931 – July 27, 2019) [1] was an American physicist who, with John Bardeen and Leon Cooper, was a recipient of the 1972 Nobel Prize in Physics for developing the BCS theory, the first successful quantum theory of ...
Charge density wave. A charge density wave (CDW) is an ordered quantum fluid of electrons in a linear chain compound or layered crystal. The electrons within a CDW form a standing wave pattern and sometimes collectively carry an electric current. The electrons in such a CDW, like those in a superconductor, can flow through a linear chain ...
