Summary

A chaotic regime maximized stored energy while suppressing fluctuations in the model.

A periodically kicked, all-to-all interacting qubit battery left its permutation-symmetric subspace when disorder was added. In the large-disorder model, random-matrix theory predicts maximum stored energy, negligible fluctuations and ergotropy close to the stored energy during noisy storage. This is a theoretical many-body result, not a device demonstration.

Why it matters

A chaotic regime maximized stored energy while suppressing fluctuations in the model.

Limits and context

  • This is a theoretical many-body result, not a device demonstration.

Key claims
