Information loss, mixing and emergent type III1 factors

open access: yesJournal of High Energy Physics, 2023
A manifestation of the black hole information loss problem is that the two-point function of probe operators in a large Anti-de Sitter black hole decays in time, whereas, on the boundary CFT, it is expected to be an almost periodic function of time.

Pure Maps between Euclidean Jordan Algebras [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
We propose a definition of purity for positive linear maps between Euclidean Jordan Algebras (EJA) that generalizes the notion of purity for quantum systems.

Note on complexity of quantum transmission processes

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
In 1989, Ohya propose a new concept, so-called Information Dynamics (ID), to investigate complex systems according to two kinds of view points. One is the dynamics of state change and another is measure of complexity.

Crossed products, conditional expectations and constraint quantization

open access: yesNuclear Physics B
Recent work has highlighted the importance of crossed products in correctly elucidating the operator algebraic approach to quantum field theories. In the gravitational context, the crossed product simultaneously promotes von Neumann algebras associated ...

When left and right disagree: entropy and von Neumann algebras in quantum gravity with general AlAdS boundary conditions

open access: yesJournal of High Energy Physics
Euclidean path integrals for UV-completions of d-dimensional bulk quantum gravity were recently studied in [1] by assuming that they satisfy axioms of finiteness, reality, continuity, reflection-positivity, and factorization.
