The Schwinger model, quantum electrodynamics in 1+1 dimensions, shares several features with quantum chromodynamics (QCD) making it an attractive testing ground for quantum simulations. In particular, the string-breaking process is a key feature due to its similarity with the dynamics of QCD hadronization. This talk will focus on exploring modifications to the string-breaking mechanism due to the presence of an external medium. The real-time dynamics of the Schwinger model as an open quantum system can be described by a Lindblad evolution equation in the high-temperature limit. In addition, I will discuss general aspects of non-equilibrium dynamics in the Schwinger model as well as estimates of Trotter errors relevant for quantum simulations.
