Description
The Z3 Schwinger model describes an approximation of one-dimensional quantum electrodynamics, which is able to capture non-perturbative features such as confinement and string breaking. We present the simulation of its quench dynamics on a digital noisy Rydberg atom platform, aiming at the observation of multiple dynamical quantum phase transitions. In order to reach long-time dynamics, we exploit an encoding dictated by the symmetries, combined with a circuit compression procedure. Focusing on the evolution of the Dirac vacuum by means of a Hamiltonian depending on a negative mass parameter, we observe resonant Rabi oscillations between the Dirac vacuum and mesonic states, in which we can clearly detect multiple dynamical phase transitions.
