The laws of Quantum Mechanics have helped scientists to unravel the behaviour of nature at its most fundamental scales. However, quantum phenomena are often difficult to understand and simulations provide a useful framework for their study. But when dealing with large quantum systems, the computational cost of a computer simulation becomes unfeasible. A proposal to face this problem is the notion of a Quantum Simulator, a controllable device governed itself by the laws of Quantum Mechanics that allows to replicate the conditions of other systems from condensed matter or high energy physics. A novel and intriguing application of Quantum Simulators is the study of particles in a cosmological context. Our research is aimed to gain some insight into how particles behave in an homogeneous, isotropic and expanding universe in order to propose a setup for the observation of exotic effects such as cosmological horizons or particle creation.
