Higher-Dimensional Test of the Holographic Dual of Entanglement Cohomology

We extend the holographic test of entanglement cohomology from $d=2$ to higher-dimensional conformal field theories. For a $d$-dimensional CFT with a spherical entangling region $A$, the vacuum modular Hamiltonian is known explicitly, and the boundary relative entropy of a primary-operator perturbation can be computed...

Cohomological Aspects of Entanglement Entropy: From Information Theory to Noncommutative Geometry

We develop a cohomological framework for entanglement entropy that unifies perspectives from information theory, operator algebras, and noncommutative geometry. Starting from the information-theoretic characterization of entropy as a 1-cocycle, we show how this structure generalizes to the quantum setting through Hochs...
