Abstract
We give an overview on our current experiments with Bose-Fermi
degenerate mixtures in a one dimensional (1D) optical lattice. Our
system consists of a Fermi gas of
40K atoms and a
Bose-Einstein condensate of
87Rb. The two species are
simultaneously trapped in a combined magnetic and optical lattice
potential. We have investigated the thermodynamical properties of
the mixture in a tight lattice and observed a change in the
density of states. This is a signature of a quasi two dimensional
confinement of the atoms in the lattice sites. We also discuss the
mechanical stability of the mixture in presence of the 1D lattice.
