Description:
The hole-doped cuprate high-temperature superconductors enter the pseudogap regime as their superconducting critical temperature, Tc, falls with decreasing hole density. Recent x-ray scattering experiments in YBa2Cu3O(6+x) observe incommensurate charge-density wave fluctuations whose strength rises gradually over a wide temperature range above Tc, but then decreases as the temperature is lowered below Tc. We propose a theory in which the superconducting and charge-density wave orders exhibit angular fluctuations in a six-dimensional space. The theory provides a natural quantitative fit to the x-ray data and can be a basis for understanding other characteristics of the pseudogap.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hayward, Lauren E -- Hawthorn, David G -- Melko, Roger G -- Sachdev, Subir -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1336-9. doi: 10.1126/science.1246310.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics and Astronomy, University of Waterloo, Waterloo, Ontario N2L 3G1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653030" target="_blank"〉PubMed〈/a〉
