DESCRIPTION:16.1.18 Dr. Philipp Preiss  **Tuesday\, 3:30pm\, R
 UTHERFORD Seminar room**\nHeidelberg University\, 
 Germany \n\n\nUltracold quantum gases in optical p
 otentials have achieved spectacular progress in th
 e experimental simulation of complex quantum syste
 ms. Complementary to many-body experiments\, mesos
 copic systems comprised of a small number of atoms
  offer the possibility to study entangled quantum 
 states with an exceptional degree of versatility a
 nd control.\nWe have implemented a highly tunable 
 platform to study such correlated few-fermion syst
 ems. Using reconfigurable optical microtraps\, we 
 prepare quantum states of 6Li atoms with a determi
 nistic atom number and spin configuration and tune
  interactions via a magnetic Feshbach resonance. A
  novel readout scheme with single-particle sensiti
 vity allows us to measure spin-resolved correlatio
 n functions in position and in momentum space.\nSu
 ch correlators characterize few-body systems via t
 he coherence and symmetry of the wavefunction. Foc
 using on the Fermi-Hubbard double-well\, we observ
 e high-contrast interference of indistinguishable 
 fermions\, the build-up of correlations due to int
 eractions\, and the emergence of entanglement betw
 een particles. Our techniques can be applied to la
 rger systems to characterize many-body phases via 
 their higher-order correlation functions.
