Those conditions foster strong correlations among the electrons, inducing superconductivity and other novel physics. Quanta Magazine, "What’s the Magic Behind Graphene’s ‘Magic’ Angle?," 28 May 2019 For example, successfully simulating a superconductor with such a device would reveal the quantum mechanics of high-temperature superconductivity. Peter Byrne, Quanta Magazine, "Quantum Computing Without Qubits," 22 Jan. 2015 The problem had eluded explanation since superconductivity was discovered in 1911. New York Times, "David Pines, 93, Insightful and Influential Physicist, Dies," 11 May 2018 One of Buck’s wild ideas was based on a property called superconductivity: the disappearance of electrical resistance in some materials when they are cooled to an extremely low temperature (think -450 Fahrenheit). Phil Lapsley, WSJ, "‘The Cryotron Files’ Review: Taking the Cold War to Subzero," 11 Oct. 2018 But in superconductivity—a state of matter that, at least for now, requires very low temperatures—electrons learn to cooperate. Frank Wilczek, WSJ, "Swimming on Atomic and Cosmic Levels," 9 Aug. 2018 David Hsieh, a condensed matter physicist at the California Institute of Technology, creates photoinduced superconductivity in a type of material (known as a Mott insulator) that becomes insulating at very cold temperatures. Neil Savage, Scientific American, "What Are the Limits of Manipulating Nature?," 8 May 2018 Unfortunately, the superconductivity thereby induced does not last much longer. Neil Savage, Scientific American, "What Are the Limits of Manipulating Nature?," 8 May 2018 This discovery that graphene is capable of superconductivity opens up a new avenue of research for superconductor scientists. Avery Thompson, Popular Mechanics, "Researchers Discover Graphene Is a Superconductor," 7 Mar. 2018
