Annalen der Physik, Volume 538, Issue 6, June 2026.This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.

Work Versus Force: Simultaneous Processes for Describing Interactions
Advanced Physics Research, Volume 5, Issue 6, June 2026.ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

Principle of «Observability»: Why Cannot the Theory of the Infinite Universe be Realized?
RUDN Journal of Philosophy, 2009 The present work demonstrates that all cosmological theories obey an epistemological relation: all steps cosmology makes in the direction of acquiring the status of a natural science are inversely proportional to its steps in the direction of allowing ...

Spinning Systems in Quantum Mechanics: An Overview and New Trends
UniverseThe study of spinning systems plays a question of interest in several research branches in physics. It allows the understanding of simple classical mechanical systems but also provides us with tools to investigate a wide range of phenomena, from ...

Cosmological comoving behavior of the configurational entropy
Physics Letters B, 2019 It has been shown that a functional dependence of the configurational entropy (CE) density exhibits a cosmological comoving behavior related to the scale parameter, a, of the FRW flat universe.

The IXPE Science of Pulsars and Their Nebulae
GalaxiesPulsars (PSRs) and Pulsar Wind Nebulae (PWNe) form some of the most interesting high-energy astrophysical systems. Their prominent synchrotron emission makes them ideal candidates for polarimetry.
