Riassunto
The goal of this thesis is to prepare the necessary tools and methods for a long-term project that aims to achieve a Rydberg Atomtronics circuit experimentally. The essential tools required for this project include dipole traps for trapping atoms, lasers for driving them from ground to Rydberg state and vice versa, and a detection system. I was involved in building and characterizing a dipole trap. In this process, I aimed to determine the loading time and the number of atoms trapped.
Three channels are necessary to control the state of the atoms. One that is resonant with the ground-Rydberg transition, thus allowing us to excite an atom in the Rydberg state; one that is detuned from the transition, so it can be used for conditioned excitations (using facilitation). Finally, a last (dissipation) channel is required, which allows us to artificially control the lifetime of the Rydberg state and so speed up the dynamics. In this thesis all of them are realized and I conclude by showing some results obtained on a many-body disordered system, experimentally
demonstrating that the above requirements can be simultaneously satisfied in our setup.
