Generation of arbitrary cylindrical vector beams using mode-converting metasurfaces Faris Alsolamy and Anthony Grbic Phys. Rev. Applied 22, 014001 (2024) – Published 1 July 2024 Recent theoretical developments have demonstrated that the optimal field profile for coupling circular apertures within the Fresnel zone is a generalized cylindrical vector beam (CVB), composed of Bessel beams with different complex weights. However, there has not been a systematic method to generate such generalized CVBs. This study uses mode-converting metasurfaces to control the modal distribution within a cylindrical cavity to generate generalized CVBs, a milestone in the development of next-generation wireless power transfer operating in the Fresnel zone. Furthermore, this method allows exploration of CVBs that can be optimized and tailored for specific applications or functions.

Applied 22, L011001 (2024) – Published 30 July 2024 According to textbooks, the transmission of a (quasi)particle through or over a potential barrier is symmetric, i.e. the same whether incident from the right or left. The authors predict that the conventional wisdom does not hold for magnon transistors with metallic gates, because the chiral damping due to eddy currents asymmetrically suppresses the reflection of magnons by obstacles. Nonreciprocal spin transport based on this effect could be interesting for applications, and the predictions here might be valid for other chiral objects as well.

This configuration provides a path toward quantum-limited detection of microwave photons. The detector is used to resolve precisely the motion of a magnetically levitated superconducting microsphere. In addition to advancing magnetic field sensing at ultralow temperatures, this innovative platform has the potential to generate and measure nonclassical mechanical states of microgram-scale masses.

Applied 22, 014082 (2024) – Published 31 July 2024 A promising branch of neuromorphic computing aims to perform cognitive operations in hardware, leveraging the physics of efficient and well-established nanodevices. This work presents a reconfigurable classifier, based on a network of magnetic tunnel junctions, that can learn to classify spoken vowels. In this task the hardware network surpasses multilayered software neural networks with the same number of trained parameters. These results, obtained using the same devices and working principle employed in industrial spin-transfer-torque magnetic random-access memory, constitute an important step toward the development of large-scale neuromorphic networks based on established technology.

In this study the authors introduce planar chirality as a quantitative geometric measure of chirality for two-dimensional objects. They apply this measure to evaluate the chirality of nanometer-sized structures with an electron microscope. They employ an innovative electron-optics device, the orbital-angular-momentum sorter, which applies a log-polar conformal mapping to the electron wave function and reaches near-optimal resolution in orbital angular momentum.
