Louis Taillefer Condensed matter physics

Louis Taillefer investigates why some materials exhibit remarkable electronic properties, such as magnetism and superconductivity. In the last decade, he has specialized in superconductors, materials that conduct electricity without any resistance. A team of CIFAR researchers and collaborators led by Taillefer made a major breakthrough by observing “quantum oscillations” in a high-temperature superconductor, providing direct insight into the nature of electron behaviour in these materials. Taillefer is aiming to understand how to make these superconductors useful for practical purposes such as power transmission, levitating trains, magnetic medical imaging, wireless communications, and much more.
