    "abstract": "We study correlations of observables in energy eigenstates of chaotic systems\nof a large size $N$. We show that the bipartite entanglement of two subsystems\nis quite strong, whereas macroscopic entanglement of the total system is\nabsent. It is also found that correlations, either quantum or classical, among\nless than $N/2$ points are quite small. These results imply that chaotic states\nare stable. Invariance of these properties under local operations is also\nshown.",
