Optical cloaking allows objects to be hidden in plain sight or to become invisible by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, like in the "Harry Potter" books, researchers in recent years have started realizing cloaks that shield objects from view by controlling the flow of electromagnetic radiation around them. In … [Read more...] about Bending light for safer driving; invisibility cloaks to come? Optical cloaks hide objects in plain view by controlling the flow of electromagnetic radiation around them
Quantum-nonlocality at all speeds
The phenomenon of quantum nonlocality defies our everyday intuition. It shows the strong correlations between several quantum particles some of which change their state instantaneously when the others are measured, regardless of the distance between them. While this phenomenon has been confirmed for slow moving particles, it has been debated whether nonlocality is preserved … [Read more...] about Quantum-nonlocality at all speeds
Inducing and tuning spin interactions in layered material: Spin-manipulation permits potential applications in energy-efficient spintronics
Magnetic-spin interactions that allow spin-manipulation by electrical control allow potential applications in energy-efficient spintronic devices. An antisymmetric exchange known as Dzyaloshinskii-Moriya interactions (DMI) is vital to form various chiral spin textures, such as skyrmions, and permits their potential application in energy-efficient spintronic devices. Published … [Read more...] about Inducing and tuning spin interactions in layered material: Spin-manipulation permits potential applications in energy-efficient spintronics
