Harris' criterion and Hardy inequalites on graphs
Simon Murmann, Marcel Schmidt
In this paper we give a version of Harris' criterion for determining within on discrete spaces. Moreover, we provide a converse via Hardy inequalities involvi…
Antiferromagnetic Heisenberg Spin Chain of a Few Cold Atoms in a One-Dimensional Trap
Simon Murmann, Frank Deuretzbacher, Gerhard Zürn +5
We report on the deterministic preparation of antiferromagnetic Heisenberg spin chains consisting of up to four fermionic atoms in a one-dimensional trap. These chains are stabiliz…
Two Fermions in a double well: Exploring a fundamental building block of the Hubbard model
Simon Murmann, Andrea Bergschneider, Vincent M. Klinkhamer +3
We have prepared two ultracold fermionic atoms in an isolated double-well potential and obtained full control over the quantum state of this system. In particular, we can independe…
Pairing in few-fermion systems with attractive interactions
G. Zürn, A. N. Wenz, S. Murmann +3
We have studied quasi one-dimensional few-particle systems consisting of one to six ultracold fermionic atoms in two different spin states with attractive interactions. We probe th…
From Few to Many: Observing the Formation of a Fermi Sea One Atom at a Time
A. N. Wenz, G. Zürn, S. Murmann +3
Knowing when a physical system has reached sufficient size for its macroscopic properties to be well described by many-body theory is difficult. We investigate the crossover from f…
Coherent molecule formation in anharmonic potentials near confinement-induced resonances
S. Sala, G. Zürn, T. Lompe +5
We perform a theoretical and experimental study of a system of two ultracold atoms with tunable interaction in an elongated trapping potential. We show that the coupling of center-…
