Energy contribution of a point interacting impurity in a Fermi gas
Thomas Moser, Robert Seiringer
We give a bound on the ground state energy of a system of non-interacting fermions in a three dimensional cubic box interacting with an impurity particle via point interactions…
Stability of the 2+2 fermionic system with point interactions
Thomas Moser, Robert Seiringer
We give a lower bound on the ground state energy of a system of two fermions of one species interacting with two fermions of another species via point interactions. We show that th…
Stability of a fermionic particle system with point interactions
Thomas Moser, Robert Seiringer
We prove that a system of fermions interacting with an additional particle via point interactions is stable if the ratio of the mass of the additional particle to the one of th…
Triviality of a model of particles with point interactions in the thermodynamic limit
Thomas Moser, Robert Seiringer
We consider a model of fermions interacting via point interactions, defined via a certain weighted Dirichlet form. While for two particles the interaction corresponds to infinite s…
Superfluidity and BEC in a Model of Interacting Bosons in a Random Potential
Martin Könenberg, Thomas Moser, Robert Seiringer +1
We present a mathematically rigorous analysis of the superfluid properties of a Bose-Einstein condensate in the many-body ground state of a one-dimensional model of interacting bos…
