Strength functions, entropies, and duality in weakly to strongly interacting fermionic systems
Strength functions, entropies, and duality in weakly to strongly interacting fermionic systems
We revisit statistical wave function properties of finite systems of interacting fermions in the light of strength functions and their participation ratio and information entropy. For weakly interacting fermions in a mean-field with random two-body interactions of increasing strength lambda, the strength functions F(k) (E) are well known to change, …
