Dealing with the unique situation of partial lock downs worldwide and home office solutions at our Institute due to the current spreading of the Covid 19 virus, we are now holding our group seminars and journal clubs via video conference.
This procedure enables us to continue our research, enhance discussions and exchange important information.


The strong background fluorescence of adjacent layers inherently limits
the single-particle resolved microscopy of quantum gases to a single
two-dimensional layer. Methods to access multilayer systems are scarce
and unreliable, in particular in combination with ultracold fermions. In
the Lithium-Lab we recently implemented a highly-stable bichromatic
superlattice in the vertical direction to realize tunable bilayer
systems. We use robust charge pumping to separate two layers by 21um.
The large separation enables independent microscopy of each layer with
high fidelity. This allows the study of bilayer Fermi-Hubbard systems or
the spin-resolution of two-dimensional systems. A review on the
technical challenges and insights gained throughout the development of
this superlattice and technique will be given.
