Cuprate superconductors have critical superconducting temperatures — the point at which their electrical...
In
cuprate superconductors, another state blocks and interacts with superconductivity: the charge - density - wave, in which the electrons assume a static pattern, different from the pattern that the material's crystal structure defines.
The latest breakthrough in superconductors, which will be published March 20 in Science, answers a key question on the microscopic electronic structure of
cuprate superconductors, the most celebrated material family in our quest for true room - temperature superconductivity.
We have directly determined the structural dynamics of such a nonequilibrium phase transition in
a cuprate superconductor.
That is, until Comin's latest results in Science, which show that
the cuprate superconductor in question has a stripe - like pattern rather than a checkerboard one.
