Unitary-orbit classification and a refinement theorem for context-independent projective probabilities

Michael P. Rubin

Let $H$ be a finite-dimensional complex Hilbert space, and let $w (P, M)$ be a normalized probability weight assigned to an outcome projection $P$ as it occurs in a…

A uniqueness theorem for the variational free energy decomposition

Michael P. Rubin

For a finite system with reference measure $p$ and positive weight $ℓ$ , the variational free energy $F (Q; p, ℓ) = D (Q ∥ p) - E_{Q} [lo g ℓ]$ satisfies the exact identity $\log Z(…
