Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.

Electrons Line Dance in a Superconductor

July 14, 2020 sarah Jonas Superconductivity

Scientists have confirmed a theoretical prediction for high-temperature superconductors. In a superconductive state, like-charged electrons overcome their repulsion to pair up and flow freely. Different states of matter make superconductivity possible. One of those theorized states of matter is called a pair density wave. The scientists confirmed pair density waves using advanced microscopic imaging techniques.
