Operator-algebra RT formula

Verified source

Communications in Mathematical Physics 354 (2017), 865-912; arXiv:1607.03901. The exact complementary-recovery and fixed auxiliary-state structure is the literature basis used by the arithmetic RT volume.

Use and boundary

Supports the distinction between a fixed area operator, center sectors and the entropy of the recoverable algebra. The arithmetic 3+6 sector construction is a concrete subspace application. Static complementary recovery does not imply that a region’s present marginal autonomously predicts its future under a center-mixing Hamiltonian.
