Low-loss and polarization insensitive 32 x 4 optical switch for ROADM applications
Reconfigurable optical add-drop multiplexers (ROADM) are critical components in flexible optical networks for the dynamic channel reassignment. A university and industrial collaborative effort in China has led to the development of a compact, integrated optical switch matrix for the ROADM applications that is both low-loss and polarization-independent.

Expanding the Hunt for Hidden Dark Matter Particles
Theoretical models of dark matter predict that its signals can be detected using low-background radiation detectors. By looking for specific types of dark matter and finding no signal, scientists operating the Majorana Demonstrator experiment have significantly narrowed the characteristics of potential dark matter particles. The results will help design future experiments.
The KDK Collaboration Identifies Rare Nuclear Decay in Long-Lived Potassium Isotope
Potassium-40 usually decays to calcium-40, but about 10 percent of the time it decays to argon-40 through electron capture. One variant of this decay path ends in argon-40 in its ground state.
New Theoretical Contribution Helps Examine the Internal Rotation of the Proton
The quark Sivers function describes much of the physics of how quarks are distributed in a proton whose rotation is perpendicular to its direction of motion. This function shows whether more quarks in the proton move to the right than to the left of the plane created by the proton's velocity and the direction of the proton's rotation (spin) axis.

Magnetic Microcoils Unlock Targeted Single-Neuron Therapies for Neurodegenerative Disorders
In the Journal of Vacuum Science & Technology A, researchers deploy an array of microscopic coils to create a magnetic field and stimulate individual neurons. The magnetic field can induce an electric field in any nearby neurons, the same effect created by an electrode but much more precise.
New Method Could Explore Gluon Saturation at the Future Electron-Ion Collider
Exploring the gluon saturation in large nuclei is one of the major goals of the future Electron-Ion Collider. New research proposes a novel method to probe the onset of gluon saturation by measuring the nucleon energy-energy correlation in deep inelastic scattering. This result leads to a comprehensive approach to study the universal behavior of gluon saturation.

Superconducting Electronics Show Promise for Future Collider Experiments
When superconductors encounter too much current, they can become resistive. Researchers can design microscopic electronic components that use this effect to create a switch, like a transistor. The resulting nanowire superconducting switching devices (called nano-cryotrons, or nTrons) show promise for future superconducting electronics or particle detectors.
