Translation-invariant quasi-free states for fermionic systems and the BCS approximation
Gerhard Bräunlich, Christian Hainzl, Robert Seiringer
We study translation-invariant quasi-free states for a system of fermions with two-particle interactions. The associated energy functional is similar to the BCS functional but incl…

On contact interactions as limits of short-range potentials
Gerhard Bräunlich, Christian Hainzl, Robert Seiringer
We reconsider the norm resolvent limit of with tending to a point interaction in three dimensions. We are mainly interested in potentials modelling s…
