Lasers Manipulate Copper-Based Superconductors

Facebook X LinkedIn Email
TRIESTE, Italy, July 16, 2014 — Ultrafast laser pulses can affect the properties of copper-based superconductors, a research team representing several Italian institutions has found. Cuprate superconductors function at relatively high temperatures around -200 °C. At slightly higher temperatures they retain some properties of superconductivity, a state called pseudogap. When the pseudogap material was illuminated with 100-fs pulses, the researchers said, it became more metallic. “What we induced is in fact a transient state — lasting less than a picosecond — which we realized was related to...Read full article
