Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, EarlyView.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Autonomous Constellation Fault Monitoring with Inter-satellite Links: A Rigidity-Based Approach [PDF]

arXiv
To address the need for robust positioning, navigation, and timing services in lunar environments, this paper proposes a novel fault detection framework for satellite constellations using inter-satellite ranging (ISR). Traditionally, navigation satellites can depend on a robust network of ground-based stations for fault monitoring. However, due to cost

A Conformal Transmissive Metasurface with Dual‐Band Dual‐Circularly Polarized Conversion and Low Scattering

Advanced Physics Research, EarlyView.
A conformal transmissive metasurface with the multi‐function is introduces, which could transform y‐polarized waves into right‐handed circularly polarized waves in 6.8–10.3 GHz and to left‐handed circularly polarized waves in 18.77–21.15 GHz, while vice versa for x‐polarized waves.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.
