The first experimental realization of a cold quantum gas dates back to 1995 and was awarded the Nobel prize in 2001. From that moment many experiments were realized to study the properties of these systems. Now the time is mature to fully exploit ultracold gases, both for quantum simulation and for precision measurements, thanks to the possibility to tune interactions and taylor the trapping potential. In my lecture, I will briefly describe how quantum gases are produced by cooling and manipulating atomic samples with lasers and magnetic fields, then I will report on a few experiments performed in the quantum gas group at LENS demonstrating the possibility to use ultracold quantum samples to investigate the physics of strongly correlated low dimensional systems, and to simulate extra-dimensions and synthetic magnetic field.

A very introductory description on laser cooling and manipulation of neutral particle can be found in "Laser trapping of neutral particles" by Steven Chu in Scientific American 266, 70 (1992) and in "How are temperatures close to abso- lute zero achieved and measured?" by Wolfgang Ketterle in Scientific American, 120 (2004) www.scientificamerican.com/article/how-are-temperatures-clos/ A perspective on the use of cold quantum gases as quantum simulators can be found in "Quantum Gases" by Immanuel Bloch, Science 319, 5867 (2008).
