The results confirmed that it was the superconductivity in the tubes that was driving
electron pairs together.
So figuring out what is keeping
electron pairs together at nearly 40 K in MgB2 has become the latest contest in the most competitive area of materials physics.
Not exact matches
When atoms come
together to form molecules,
electrons on different atoms
pair up to form bonds that lock the molecule
together.
Superconductivity occurs when
electrons come
together in a material in Cooper
pairs that can move unimpeded through the material.
Now, a
pair of scientists from the U.S. Department of Energy's Brookhaven National Laboratory and Ludwig Maximilian University in Munich have proposed the first solution to such subatomic stoppage: a novel way to create a more robust
electron wave by binding
together the
electron's direction of movement and its spin.
In a conventional superconductor
electrons with opposite spins are
paired together so that a flow of
electrons carries zero spin.
The ideas they worked on
together are now known as BCS theory and provide a description of the superconducting state in terms of interactions between
pairs of
electrons.
