MANIPULATION OF SKYRMIONS USING ONLY AN ELECTRIC FIELD. March 2019
Microelectric, NO CURRENT so unthinkable power savings with memory storage that is ALSO the LOGICAL BITS. Space saving.
More powerful computers, 1/2 the space or more savings, MUCH higher density of memory/logic per mm. AND taking advantage of the quantum hall effect, MUCH closer to no/low power quantum computing.
Mathematical assumptions of triangular balance in crystaline structures held this field back for probably 25 years from the first proposal in 1962.
Soon, it’s going to let your computer run off a 9V battery.
Thank you DARPA for funding this stuff.
“Determination of the orientation of the Dzyaloshinskii–Moriya vector from the local geometry”
2018 technology in production now. There’s a 5-10 year gap between theory, demo and industry but it’s there, supported by DARPA. I may be anti-war in general but my heart’s always with DARPA as they’re focused on pure R&D that leads to advancement and by sharing the burden with industry it might result in a loss of ‘secret super power” but what’s gained is good new stuff.
The future of computing / communication / etc rests NOT in super perfect silicon wafers but DIRTY metals with imperfections.
Too perfect and you reach a limit. Make it sloppy and cheap and you’ve just broken harmony and the “side effects” (such as quantum hall effect and topological insulators) which vastly open the limits of “what’s possible” in terms of speed, smaller size, low energy use, increased capabilities.
MOST symmetry *is* preserved in quantum hall and topological insulators but NOT ALL SYMMETRY.
It’s the subtle broken symmetries (lining up nicely with gauge invarience integer fractions which work to one part in a billion which is extraordinarily precise) which will bring us forward to the next era of computing.
