Nature: String theory could help explain the properties of high-temperature superconductors, writes Nature‘s Eugenie Samuel Reich. In a paper published in Physical Review Letters, Subir Sachdev of Harvard University shows that the fractionalized Fermi liquid model’s characteristics match those of a type of black hole in string theory. “We’re still a long way from saying string theory explains strange matter but we have hope,” Sachdev says. “It’s very exciting because it’s a whole new perspective.”
