The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency
Advanced Physics Research, Volume 5, Issue 6, June 2026.Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities
Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...
