The Current Experimental Status of the High Tc Problem

April 19, 2017
The American Center for Physics

Date: April 19, 2017

Speaker: Rick Greene, University of Maryland

Topic: The Current Experimental Status of the High Tc Problem

Time and Location: 1:00 p.m., with Q&A to follow in a 1st floor conference room at the American Center for Physics (www.acp.org), 1 Physics Ellipse, College Park, MD - off River Rd., between Kenilworth Ave. and Paint Branch Parkway.

Abstract: Will a room temperature superconductor soon be discovered? There is no known theoretical limitation on Tc at present. Recent work has produced a Tc of just over 200K in pressurized H3S. On the other hand, over 50,000 experimental papers have been published since 1987 on the copper oxide (cuprate) high Tc superconductors — and we still don’t understand them. In this talk, I will attempt to summarize the experimental properties of high-Tc superconductors that we presently understand and those that we don’t yet understand. I will not speculate on the "unknown unknowns", although some examples of these have appeared during the past 30 years of research.
