| Title | Liouvillian Dynamics of the Open Schwinger Model: String Breaking and Kinetic Dissipation in a Thermal Medium | ||||
| Abstract | Understanding the dynamics of bound state formation is one of the key questions in confining quantum field theories such as quantum chromodynamics. In this work, we consider a key aspect of this process within the Schwinger model: the breaking of a single string into two separated strings. We study the modification to the string breaking mechanism due to the presence of an external medium. To do this, we consider the Schwinger model as an open quantum system coupled to a thermal environment, where in the weakly coupled regime the real-time evolution can be described by a Lindblad evolution equation. We observe a delay of the string breaking due to dissipation of the string tension into the environment. We discuss how this process can be simulated on quantum computers, and perform an estimate of associated Trotter errors. | ||||
