Complete lifts from a Sasakian manifold concerning the quarter symmetric metric connection to its tangent bundle

open access: yes
The present paper aims to study the complete lifts of the quarter symmetric metric connection and we establish the interrelation between a Levi-Civita connection and a quarter symmetric metric connection on a Sasakian manifold to its tangent bundle.

Efficient Polarization‐Entangled Photon‐Pair Generation by a Fiber‐In‐Line van der Waals Material

open access: yesAdvanced Science, EarlyView.
Telecom‐wavelength polarization‐entangled photon pairs are generated in a van der Waals‐material‐integrated all‐fiber device via spontaneous parametric down‐conversion. The demonstrated fiberized quantum light source bridges emerging 2D nonlinear materials and practical quantum photonic systems, opening new opportunities for scalable fiber‐based ...

On weak symmetries of Kenmotsu Manifolds with respect to quarter-symmetric metric connection [PDF]

open access: yes
The aim of this paper is to study weakly symmetries of Kenmotsu man- ifolds with respect to quarter-symmetric metric connection. We investigate the properties of weakly symmetric, weakly Ricci-symmetric and weakly concircular Ricci-symmetric Kenmotsu ...

In Situ Profiling of Nanoscale Strains Uncovers Mechano‐Architectural Predictors of Aging and Osteoarthritis Emergence

open access: yesAdvanced Science, EarlyView.
In situ mechanical loading of osteoarthritis‐prone murine knee joints reveals that spatial alterations in subchondral plate microarchitecture precede cartilage loss and promote a shift from coordinated epiphyseal strain dissipation in healthy joints to focal subchondral strain concentration in osteoarthritis‐prone joints.

Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

open access: yesAdvanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies

open access: yesAdvanced Science, EarlyView.
A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

Printable Piezoresistive Hybrid Hydrogels Based on 2D MoS2 for Flexible Pulse Sensing

open access: yesAdvanced Science, EarlyView.
Hybrid 1T‐MoS2‐based hydrogels are engineered through UV curing and 3D printing to achieve tunable electromechanical properties for wearable sensing. These soft architectures enhance mechanical stability and reproducible piezoresistive responses within the physiological pressure range.

Giant Magneto‐Optical Effects in Two‐Dimensional Flat‐Band Antiferromagnets

open access: yesAdvanced Science, EarlyView.
RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.
