On the Weakness of Short-Range Interactions in Fermi Gases
Marcel Griesemer, Michael Hofacker
Ultracold quantum gases of equal spin fermions with short range interactions are often considered free even in the presence of strongly binding spin-up-spin-down pairs. We describe…

From Short-Range to Contact Interactions in Two-dimensional Many-Body Quantum Systems
Marcel Griesemer, Michael Hofacker
Quantum systems composed of distinct particles in with two-body contact interactions of TMS type are shown to arise as limits - in the norm resolvent sense - of Schrödin…

From Short-Range to Contact Interactions in the 1d Bose Gas
Marcel Griesemer, Michael Hofacker, Ulrich Linden
For a system of bosons in one space dimension with two-body -interactions the Hamiltonian can be defined in terms of the usual closed semi-bounded quadratic form. We approxi…
