Nanoparticles control flow of light like road signs direct traffic
Physicists at The Australian National University (ANU) have developed tiny translucent slides capable of producing two very different images by manipulating the direction in which light travels through them. As light passes through the slide, an image of Australia can be seen, but when you flip the slide and look again, an image of the […]
Computational sleuthing confirms first 3D quantum spin liquid: Numerical detective work verifies liquidlike magnetic order in prior experiments
Computational detective work by U.S. and German physicists has confirmed cerium zirconium pyrochlore is a 3D quantum spin liquid. Despite the name, quantum spin liquids are solid materials in which quantum entanglement and the geometric arrangement of atoms frustrate the natural tendency of electrons to magnetically order themselves in relation to one another. The geometric […]
Event horizons are tunable factories of quantum entanglement: Physicists’ research findings open a promising avenue for confirming the quantum origin of the Hawking radiation
LSU physicists have leveraged quantum information theory techniques to reveal a mechanism for amplifying, or “stimulating,” the production of entanglement in the Hawking effect in a controlled manner. Furthermore, these scientists propose a protocol for testing this idea in the laboratory using artificially produced event horizons. These results have been recently published in Physical Review […]
