What observables are indicative of BCS Cooper pair condensation?
"Thought" experiments and "numerical" experiments are allowed.
This question is motivated by the question Has BCS Cooper pair condensate been observed in experiment?Has BCS Cooper pair condensate been observed in experiment? , and by our recent research on anyon superfluidity where anyons are emergent from a fermion system.
"BCS Cooper pair condensation" has a formal theoretical description. Here I am looking for an experiemental or numerical definition of "BCS Cooper pair condensation".
