Cooling by laser beam
(Scuola Internazionale Superiore di Studi Avanzati) A laser pulse that for a few picoseconds transforms a material into a high-temperature superconductor. Different experiments have unveiled this interesting phenomenon, with potential applicative implications. Research carried out by SISSA scientists a year ago had already provided several basic principles of the phenomenon. A new study published on "Physical Review Letters" now clarifies other important aspects.
