Enhancement of Bipartite Entanglement in Three Level Lasers via Kerr Resonator Coupled to Squeezed Vacuum Reservoir

This paper demonstrates that bipartite entanglement in a three-level cascade laser can be significantly enhanced by combining Kerr nonlinearity, squeezed vacuum reservoirs, and coherent pumping, while cavity losses act as a limiting factor, thereby establishing a promising platform for generating bright continuous-variable entangled light for quantum information applications.

What Grounds Dimension? Dynamical Accessibility and Ontological Commitment in Physics

This paper argues that dimension lacks inherent ontological fundamentality and gains physical significance only when its attribution is grounded in dynamically accessible structures and processes rather than mere mathematical representation.

Stress Analysis of Anisotropic Inclusion Problems Using Complex-Variable Methods

This paper presents an analytical method using complex-variable techniques, combining the Airy stress function for an isotropic matrix and Lekhnitskii's formalism for an anisotropic inclusion, to derive stress fields in a circular inclusion embedded in an infinite medium under uniform far-field stresses by determining series coefficients through interface continuity and boundary conditions.

Observation of intrinsic transverse thermoelectricity in anisotropic semimetals

Researchers demonstrate that intrinsic in-plane anisotropy in van der Waals semimetals enables zero-field transverse thermoelectric cooling, successfully driving localized hotspots below ambient temperature to overcome Joule heating in nanoscale devices.

A Threshold-Function Formulation for Local Helicity as an Independent Constraint: Formal Branch Separation, Asymptotic Constant Limits, and a Species-Organized Experimental Analogue

This paper formalizes local helicity as an independent branch-selection constraint defined by a geometry-dependent threshold function that converges to a constant limit under specific separation conditions, while validating this threshold-function logic through a high-fidelity experimental analogue using TCV L-H transition data organized by species mass number rather than as a direct proof of a universal plasma law.

Wear mode transition Fe-Cr-C welded layers under dry and wet abrasive contact conditions

This study demonstrates that transitioning from dry to wet abrasive contact conditions fundamentally alters the wear mechanism of Fe-Cr-C hardfacing layers from micro-contact carbide-matrix support to three-body micro-cutting and spalling, necessitating a combined analysis of microstructural geometry and friction signal characteristics rather than wear volume alone to accurately predict material performance.

Geometry-controlled effects of circular and semi-circular laser textures on the tribological behavior of G13Cr14Co12Mo5Ni2 bearing steel

This study demonstrates that semi-circular laser textures outperform circular ones on G13Cr14Co12Mo5Ni2 bearing steel by leveraging asymmetric geometry to enhance debris accommodation, reduce ploughing damage, and generate stronger local positive pressure for superior lubricated tribological performance.
