Non-Kolmogorov-Arnold-Moser Quantum Sensors for Quantum Parameter Estimation

Naga Dileep Varikuti, Sourav Manna, Athreya Shankar +2

Non-KAM (Kolmogorov-Arnold-Moser) systems, when subjected to weak time-dependent perturbations, exhibit an abrupt transition to classical chaos through the breakdown of invariant p…
