“Power-law decay of mixed states in kicked top model’s semiclassical limit”

https://pubmed.ncbi.nlm.nih.gov/38115398

This study analyzes the properties of mixed eigenstates in the kicked top model, a time-dependent Hamiltonian system, and finds that the relative fraction of mixed states exhibits a power-law decay as the system size increases, suggesting that only purely regular and chaotic eigenstates remain in the semiclassical limit.
