Latest Superconductivity Stories
Superconducting materials, which transmit power resistance-free, are found to perform optimally when high- and low-charge density varies on the nanoscale level.
Physicists are divided on whether string theory is a viable theory of everything, but many agree that it offers a new way to look at physical phenomena that have otherwise proven difficult to describe.
U.S., German and Austrian physicists studying the perplexing class of materials that includes high-temperature superconductors are reporting this week the unexpected discovery of a simple "scaling" behavior in the electronic excitations measured in a related material.
In a major step toward understanding the mysterious "pseudogap" state in high-temperature cuprate superconductors, a team of Cornell, Binghamton University and Brookhaven National Laboratory scientists have found a "broken symmetry," where electrons act like molecules in a liquid crystal: Electrons between copper and oxygen atoms arrange themselves differently "north-south" than "east-west."
Binghamton University physicist Michael Lawler and his colleagues have made a breakthrough that could lead to advances in superconductors.
Scientists have been trying for some 20 years to understand why the low temperature at which copper-oxide superconductors carry current with no resistance can't be increased to be closer to room temperature.
Scientists at JILA, working with Italian theorists, have discovered another notable similarity between ultracold atomic gases and high-temperature superconductors, suggesting there may be a relatively simple shared explanation for equivalent behaviors of the two very different systems.
When high-temperature superconductors were first announced in the late 1980s, it was thought that they would lead to ultra-efficient magnetic trains and other paradigm-shifting technologies.
What could be better than diamond when it comes to a superhard material for electronics under extreme thermal and pressure conditions?
Materialâ€™s fluctuating response to a magnetic field could lead to switchable superconducting wires.
An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
