The goal of this project is to engineer interactions between ultracold atoms in table top experiments to emulate and study typical phenomena of field theory and strongly correlated matter. Most relevant example is the decay of metastable field, commonly known as False Vacuum Decay. The power of this approach is twofold: first, the esquisite control of experimental parameters allows a fine tuning of coupling constants and a dedicated focus on significant system observables; secondly, the typical tools of atomic Physics and the accessible length and energy scales allow a direct access to particle detection and numerous atomic properties, as dynamics, correlation function and excitation spectra.
