This limitation in movement could be present in other states of electron pairs, such as the Cooper pairs of superconductivity, mainly in high Tc Superconductivity, for example.
Later, Animalou [14] and Animalou and Santilli [15] extended the model to consider the Cooper pair in superconductivity as a hadronic bound state of two identical electrons.
In every device made the right way, unpaired electrons were very rare, allowing manipulation of single Cooper pairs over long time scales and over a wide range of temperature.
Levy says these electron pairs resemble tightly bound molecules; the partners in Cooper pairs spread farther apart.
Such tests have revealed that electrons in the cuprates and iron-based compounds appear to travel in pairs while superconducting, but not in the way traditional Cooper pairs work.
The collective flow of Cooper pairs results in the most famous feature of a superconductor and the feature that draws the most interest in terms of energy efficiency: the flow of electrical current without any measurable loss of energy, or true zero resistance.
Study of such Cooper pairs could shed light on superconductivity, he suggests.
Pions, consisting of pairs of quarks, play the same sort of simplifying role as Cooper pairs in superconductivity theory.
That finding confirms a theoretical prediction that helium-3 becomes a superfluid only if its atoms are coupled in what are known as Cooper pairs.
To get superconductivity, electronsmust cooperate in pairs, called Cooper pairs.
The basic theory of superconductivity,worked out 30 years ago, states that electrons in a crystal can communicate with one another by forming what are known as Cooper pairs.
According to Steglich, this question of singlet versus triplet state for the Cooper pairs is one of two that have "initiated a lively and, to some extent, controversial debate.
