Scientists capture ultrafast snapshots of light-driven superconductivity

Scientists capture ultrafast snapshots of light-driven superconductivity | Physics | Scoop.it
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.
Mikko Hakala's insight:

X-ray studies bring insight into developing room-temperature superconductors. This laser pump - x-ray probe experiment showed that the appearance of superconductivity is not related to lattice distortions (the distortions persist longer than the melting of charge stripes, i.e. the point where superconductivity emerges).

 

The findings are relevant for understanding generally the mechanism of superconductivity in layered copper oxide materials, and in the new field of light-induced superconductivity.

 

The experimental x-ray method used was resonant soft x-ray diffraction.

Scientists open a new window into quantum physics with superconductivity in LEDs

Scientists open a new window into quantum physics with superconductivity in LEDs | Physics | Scoop.it
A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement.

Mikko Hakala's insight:

Put a superconductor in contact with a semiconductor LED. According to the article, when Cooper pairs are injected into LED the emitted photons are entangled. Interesting opening.
