X-rays reveal how rapidly vanishing 'charge stripes' may be
behind laser-induced high-temperature superconductivity
A new study pins down a major factor behind the appearance
of superconductivity—the ability to conduct electricity with 100 percent
efficiency—in a promising copper-oxide material.
Scientists used carefully timed pairs of laser pulses at
SLAC National Accelerator Laboratory's Linac Coherent Light Source (LCLS) to
trigger superconductivity in the material and immediately take x-ray snapshots
of its atomic and electronic structure as superconductivity emerged.
