Previously, the cooper pair effect was not associated with photons.
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.

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.
For the high-temperature superconductors, we theorists are embarrassed to admit that after more than 20 years, we still aren't sure how these Cooper pairs form.
