Superconducting coherence length
- Superconducting coherence length
A Superconducting coherence length, usually denoted as , can be interpreted in two different ways:
* It gives approximate spatial dimension (size) of the Cooper pair,
* It sets the length scale on which the superconducting order parameter changes considerably.
The superconducting coherence length () is one of two parameters in a Ginzburg-Landau theory of superconductivity.
