Anyon dynamics in driven topologically ordered quantum systems — •Francesco Petiziol — Technische Universität Berlin, Institut für Physik und Astronomie, Hardenbergstr. 36, 10623 Berlin

Quantum systems with topological order exhibit long-range entanglement and host quasiparticle excitations with unconventional quantum statistics -- anyons. These features make them of great interest from both fundamental and quantum-technological perspectives. Recent progress in realizing topological order in quantum simulators highlights the importance and the challenge of understanding the behaviour of such systems under non-equilibrium conditions. Focusing on Kitaev's toric code, I will discuss how external driving, either coherent or incoherent, can impact and alter anyon properties. Examples include the emergence of more complex anyon classes from simpler ones, the dynamics of entanglement under driven anyon proliferation, and opportunities for controlled anyon transport.
