Crossed products, conditional expectations and constraint quantization

Nuclear 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 ...

Rocking and Rolling of Rigid Polygons Under Seismic Excitation

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We present an event driven analytical framework for rigid cyclic polygons subjected to horizontal ground excitation in which uplift, impact, and successive pivot switching are treated within a unified non‐smooth dynamical description. Rolling is defined as a sequence of energetically admissible transitions between neighbouring vertices tied to

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

Large‐Scale Moisture Circulation Index Related to Socioeconomic Drought and Its Subseasonal Forecast Skill in the Asian Monsoon Rainy Season

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Socioeconomic drought, which occurs when water demand exceeds available supply and often leads to water withdrawal restrictions, affects water resource management. However, the relationship between large‐scale moisture circulation and the occurrence of socioeconomic drought has not been well understood. In this study, we focused on the Yoshino

Phase space quantization, noncommutativity, and the gravitational field [PDF]

Physical Review D, 2014
In this paper we study the structure of the phase space in noncommutative geometry in the presence of a nontrivial frame. Our basic assumptions are that the underlying space is a symplectic and parallelizable manifold. Furthermore, we assume the validity of the Leibniz rule and the Jacobi identities.

Study of Free‐Space Optical Quantum Network: Review and Prospectives

Advanced Science, Volume 13, Issue 36, 29 June 2026.
Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.

Locality and causality properties of light cone string field theory [PDF]

, 2004
The recent discovery of a new maximally supersymmetric background for the type IIB superstring theory has revived the interest in light cone string field theory.

Quantization and Structure of Electromagnetic and Gravitational Fields

American Journal of Modern Physics, 2021
Following Relativistic Alpha Field Theory (RAFT) here it is started with the solution of the field parameters α and α′ in the combined electromagnetic and gravitational fields. The field parameters α and α′ are described as the functions of the particle charge, particle mass, electrical potential, gravitational potential, gravitational constant ...

On the Meaning of Localization in Non‐Local Quantum Field Theory

Annalen der Physik, Volume 538, Issue 6, June 2026.
In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...
