Article Synopsis
- The study explores how ferromagnetic order in electrostatically doped monolayer transition metal dichalcogenides (TMDs) can be controlled at zero magnetic field using local optical pumping.
- By employing circular dichroism techniques, researchers demonstrated that an optical pump can create a significant charge-carrier spin polarization, stabilizing long-range magnetic order in materials.
- The findings suggest that using local optical pumps to control magnetism could lead to advancements in spintronic and optical technologies, and offer new research opportunities in the behavior of two-dimensional electron gases.
Van der Waals (vdW) solids can be engineered with atomically precise vertical composition through the assembly of layered two-dimensional materials. However, the artisanal assembly of structures from micromechanically exfoliated flakes is not compatible with scalable and rapid manufacturing. Further engineering of vdW solids requires precisely designed and controlled composition over all three spatial dimensions and interlayer rotation.

- Color centers in diamond are potential qubits for quantum tech, but integrating them into devices is challenging.
- Researchers developed thin diamond membranes (50-250 nm) with high-quality features that facilitate this integration.
- These membranes display stable optical properties and impressive spin coherence times for individual color centers, making them promising for future quantum applications.
Integrating solid-state quantum emitters with nanophotonic resonators is essential for efficient spin-photon interfacing and optical networking applications. While diamond color centers have proven to be excellent candidates for emerging quantum technologies, their integration with optical resonators remains challenging. Conventional approaches based on etching resonators into diamond often negatively impact color center performance and offer low device yield.
