and charge density waves like to be arranged in a very specific, nanoscopic way,” explained Coslovich. “They are intertwined orders at the length scale of the waves themselves.”off with light pulses was a significant advance, enabling observations on the time scale of less than a trillionth of a second, with major advantages over previous approaches.
“When you use other methods, like applying a high magnetic field, you have to wait a long time before making measurements, so CDWs rearrange around disorder and other phenomena can take place in the sample,” he said. “Using light allowed us to show this is an intrinsic effect, a real connection betweenThe research team is excited to expand on this pivotal work, Turner said. First, they want to study how the CDWs become more organized when theis shut off with light.
“There is an overall interest in trying to do this with pulses of light on very fast time scales, because that can potentially lead to the development of superconducting, light-controlled devices for the new generation of electronics and computing,” said Coslovich. “Ultimately, this work can also help guide people who are trying to build room-temperature superconductors.”
This research is part of a collaboration between researchers from LCLS, SLAC’s Stanford Synchrotron Radiation Lightsource , UBC, Yale University, the Institut National de la Recherche Scientifique in Canada, North Carolina State University, Universita Cattolica di Brescia and other institutions. This work was funded in part by the DOE Office of Science. LCLS and SSRL are DOE Office of Science user facilities.
