Researchers experimentally investigate the impact of introducing high-density calcium on the superconductivity of calcium-intercalated bilayer graphene.

Twisted bilayer graphene defies conventional theories by exhibiting superconductivity despite a vanishingly small charge carrier velocity.

New York University’s Center for Quantum Information Physics and the University of Copenhagen’s Niels Bohr Institute have established a collaboration to develop superconductor and semiconductor materials, which could be used to enhance performance of electronics, quantum sensors, and computing capabilities, for manufacturing.

Majoranas, which fall into this category of emergent particles, can exist in certain types of superconductors and in a quantum state of matter known as a spin liquid. Two Majoranas combine to form an electron, so scientists aim to identify materials in which these Majoranas can exist separately. Doing so would enable researchers to observe the unique capabilities that these particles demonstrate on their own — including efficient methods for storing and transferring information across great distances.

MIT physicists and colleagues have created a five-lane superhighway for electrons that could allow ultra-efficient electronics and more. The work, reported in the May 9 issue of Science, is one of several important discoveries by the same team over the last year involving a material that is essentially a unique form of pencil lead.

Using the Hubbard model, Flatiron Institute senior research scientist Shiwei Zhang and his colleagues have computationally re-created key features of the superconductivity in materials called cuprates that have puzzled scientists for decades.

By tinkering with a quantum material characterized by atoms arranged in the shape of a sheriff’s star, MIT physicists and colleagues have unexpectedly discovered a new way to make a state of matter known as a strange metal. Strange metals are of interest for their unusual physics and because they have been found in the high-temperature superconductors key to a variety of applications.

In a significant development in the field of superconductivity, researchers at The University of Manchester have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.

Würzburg physicists have discovered that quantum entanglement toughens up quasiparticles against impurity scattering – even when they are subject to strong disorder.
