Reports from Cornell University Describe Recent Advances in General Science

June 6, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Science. According to news reporting originating from Ithaca, New York, by NewsRx correspondents, research stated, "The existence of electronic symmetry breaking in the underdoped cuprates and its disappearance with increased hole density p are now widely reported."

Our news editors obtained a quote from the research from Cornell University, "However, the relation between this transition and the momentum-space ((k) over right arrow -space) electronic structure underpinning the superconductivity has not yet been established. Here, we visualize the (Q) over right arrow =0 (intra-unit-cell) and (Q) over right arrow not equal 0 (density-wave) broken-symmetry states, simultaneously with the coherent. (k) over right arrow -space topology, for Bi2Sr2CaCu2O8+delta samples spanning the phase diagram 0.06

According to the news editors, the research concluded: "We show that the electronic symmetry-breaking tendencies weaken with increasing p and disappear close to a critical doping pŠ = 0.19. Concomitantly, the coherent."
