Could the combination of general relativity and quantum mechanics lead to spintronics?
Could the combination of general relativity and quantum mechanics lead to spintronics?: In Japan, Maekawa and his colleagues decided that studying how to use mechanical rotation to direct spin current could be advantageous in the development of spintronic devices that scientists think could eventually replace silicon-based electronics. “We found that we needed to add general relativity to the equation,” Maekawa says. “Dirac included special relativity, but general relativity was needed as well. We combined the two Einstein theories, and added them to the theory of quantum mechanics. This way, we added mechanical rotation to the quantum equation.”
