Modular Self-Duality, Symmetrized Relative Entropy, and Bogoliubov--Kubo--Mori Susceptibility in Quantum Field Theory
Develops modular self-duality for local states in QFT via symmetrized Araki relative entropy and defines the associated type-III BKM susceptibility, with exact quadratic realizations for free scalar fields on wedges and chiral U(1) currents on half-lines.
