Over the last decade quantum gases in optical lattices have proven to be a versatile tool for quantum simulation. Reducing the dimensions of these systems to one allows to study the famous Luttinger liquid which promises to yield insight into phenomena such as spin-charge separation.

We experimentally study the physics of quasi-one-dimensional fermionic quantum gases by loading a quantum degenerate two component gas of fermionic 40K atoms into a two-dimensional optical lattice geometry.

Here, I will report on our recent work on the characterisation of the system using a combination of high-resolution imaging and spatially resolved two-photon Raman spectroscopy.
