Anomalous Floquet Heating from Sparse Long-Range Interactions (opens in new tab)

Regular lattices of interacting particles under a periodic drive typically heat with rate $\gamma \sim e^{-\mathcal{O}(\omega)}$ which is exponentially suppressed in drive frequency $\omega$. Here, we show that sparse infinite-range interactions, which have recently become accessible in quantum simulators, can lead to anomalous heating with rate $\gamma \sim e^{-\mathcal{O}(\sqrt{\omega})}$. This anomaly originates from the broad distribution of...
