  • Quantum discovery could enable efficient battery-free, energy-harvesting devices Quantum material converts ambient alternating signals into usable direct current without magnets or bulky diodes. An international team of scientists has shown that tiny imperfections and vibrations within a quantum material can be leveraged to control a surprising quantum effect called the nonlinear Hall effect. The new discovery could pave the way for smaller and more efficient energy-harvesting devices. Impressively, according to the researchers, it could one day enable electrical devices that operate without b
