DESCRIPTION:Speaker: Selim Jochim\nhosted by Julian Léonard\nAbstract: Sta
 rting from a highly degenerate Fermi gas of atoms\, we distill quantum sta
 tes of few atoms by exquisite control of the number of bound states in an 
 optical tweezer potential. In this way we obtain close to pure quantum sta
 tes of up to 42 atoms. While such systems have a lot of similarities with
  the electrons in an atom\, or nucleons in a nucleus\, the tunability of g
 eometry and interactions\, combined with versatile manipulation and detect
 ion capabilities offer unprecedented insights. For example\, measuring all
  momenta or positions of the atoms in a spin resolved way allows us to det
 ermine correlations\, such as those that define Cooper pairs. In our ques
 t to gain better control and diagnostics\, were are currently working on n
 ew manipulation techniques that respect the symmetry of our systems: As fi
 rst steps\, we learned how to manipulate angular momentum eigenstates\, an
 d could engineer correlated states of two atoms that are described by the 
 Laughlin wave function.It is our vision to be able to measure and manipula
 te the motional state of each atom\, including the angular momentum.As fur
 ther progress is pushing the frontiers of our experimental capabilities\, 
 we have designed a new modular platform that allows to quickly exchange in
 dividual building blocks. Each module can be characterized and validated o
 ffline on a test bench. We will report our first experience with this new 
 setup.
