Pronunciación: /ˈkuːpəpɛː/

Definición de Cooper pair en inglés:


1A loosely bound pair of electrons with opposite spins and moving with the same speed in opposite directions, held to be responsible for the phenomenon of superconductivity.
Oraciones de ejemplo
  • In that model, pairs of electrons with opposite spin form so-called Cooper pairs with zero total spin.
  • Electrons in these Cooper pairs have opposite values of momentum, meaning that the pairs themselves generally have zero orbital angular momentum.
  • These electron pairs are called Cooper pairs, and as described by Schrieffer, they condense into a single state and flow as a totally directionless fluid.
1.1A loosely bound pair of atoms in a superfluid.
Oraciones de ejemplo
  • Just as in Bose-Einstein condensation, the Cooper pairs can fall into a single quantum state and thus cause a phase transition to a superconducting or superfluid phase.
  • Similarly, it is very unlikely for singlet superconductivity to appear in the ferromagnetic state because the exchange interaction forbids the formation of Cooper pairs.
  • One potential source of such particles is the stream of conjoined electrons that exist in superconductors, but no one has been able to drive a wedge between these so-called Cooper pairs.


1960s: named after Leon N. Cooper (born 1930), American physicist.
