Hi

In my book it says that a Cooper pair is formed by a single electron state and its

[tex]

\left| {k \uparrow } \right\rangle \quad \text{and} \quad \left| { - k \downarrow } \right\rangle.

[/tex]

Where does the time-reversal come into play?

Best,

Niles.

In my book it says that a Cooper pair is formed by a single electron state and its

*time-reversed*counterpart. The way I have understood it, a Cooper pair is formed by the states[tex]

\left| {k \uparrow } \right\rangle \quad \text{and} \quad \left| { - k \downarrow } \right\rangle.
