Cosmic structure formation can be described by a classical path integral formalism. We apply such a theoretical framework to predict structure formation in an initially correlated ensemble of Rydberg atoms. The free Hamiltonian motion of particles and their initial correlation function are contained in a generating functional. We model the non-classical excitation process including blockade and anti-blockade effects to emulate realistic initial conditions. Interactions between the particles are introduced via an operator acting perturbatively on the free generating functional which is evolved in time. Collective properties, such as density correlations can be extracted by applying appropriate operators.
We will discuss different experimental implementations with the aim of directly or indirectly observing the impact of initial correlations on structure formation.
