This research demonstrates that complex correlated decay dynamics in bosonic systems can be accurately modeled using established rate equations, even as interactions weaken and the system transitions from superradiance to subradiant emission. By exploiting permutational symmetry, researchers successfully reduced an otherwise intractable Hilbert space dimensionality, enabling large-scale numerical simulations without sacrificing accuracy for circuit QED experiments. These findings extend theoretical frameworks regarding collective decay while offering a simplified analytical path for understanding nuanced bosonic behaviors.
Bosonic Systems Switch Emission Modes, Mirroring Superradiance Despite Complexity

Can correlated decay in bosonic systems be accurately modelled using established tools, even when interactions weaken? Recent work demonstrates that the dynamics of these systems, transitioning from strong to subradiant emission, are indeed describable by rate equations similar to the Dicke model. This extends existing theoretical frameworks and offers a simpler path to understanding complex bosonic behaviour.
A bosonic system mirroring the Dicke model of superradiance exhibits nuanced emission behaviours dependent on interaction strength. Bennet Windt of ICFO, University of Copenhagen, Max Planck Institute of Quantum Optics, Google, The Barcelona Institute of Science and Technology, and colleagues reveal a transition from Dicke-like superradiance at strong interactions to subradiant emission with weaker interactions. Notably, the dynamics in the weaker interaction regime align with rate equations similar to the original Dicke model, despite a complex bosonic state space. These…
