2. Pairing in low density fermion systems: Open problems
Symmetric (unpolarized) systems
What is the size of the Cooper pair?
Nature 454, (2008)
- Is there a pseudo-gap phase?
What is the best way to put it in evidence experimentally?
- Response of a paired system to a weak external field, RF spectroscopy.
