Fractals are a never-ending pattern that you can zoom in on, and the image doesn’t change. Fractals can occur in two dimensions, like frost on a window, or in three dimensions, like the limbs of a tree. A recent discovery from Purdue University researchers has established that superconducting images, seen above in red and blue,Continue reading “Superconductors, 3D Disorder, Fractals…”

Adam Fenster/University of Rochester Topics: Applied Physics, Condensed Matter Physics, Materials Science, Superconductors Will a possible breakthrough for room-temperature superconducting materials hold up to scrutiny? This week researchers claimed to have discovered a superconducting material that can shuttle electricity with no loss ofContinue reading “Caveat Super…”
Fourth Signature…
Topics: Condensed Matter Physics, Superconductor, Thermodynamics Researchers in the US report that they have observed the so-called “fourth signature” of superconducting phase transitions in materials known as cuprates. The result, obtained via photoemission spectroscopy of a cuprate called Bi2212, could shed fresh light on how these materials, which conduct electricity without resistance at temperatures ofContinue reading “Fourth Signature…”
Pairs of Cooper Pairs…
Topics: Condensed Matter Physics, Solid-State Physics, Superconductors Note: I gave my research proposal last Friday. I have been answering some concerns about my proposal for the committee. I followed the outline sent to me by my advisor. I hope I’ve answered them sufficiently. I will post today and tomorrow; next week on Monday, Wednesday, andContinue reading “Pairs of Cooper Pairs…”
Kagome Metal…
Topics: Condensed Matter Physics, Materials Science, Superconductors Researchers at the Chinese Academy of Sciences have found evidence for an unusual superconducting state in CsV3Sb5, a so-called Kagome metal that exhibits exotic electronic properties. The finding could shed new light on how superconductivity emerges in materials where phenomena such as frustrated magnetism and intertwined orders playContinue reading “Kagome Metal…”
Strange Metals…
Topics: Black Holes, Modern Physics, Quantum Mechanics, Superconductors, Theoretical Physics Even by the standards of quantum physicists, strange metals are just plain odd. The materials are related to high-temperature superconductors and have surprising connections to the properties of black holes. Electrons in strange metals dissipate energy as fast as they’re allowed to under the lawsContinue reading “Strange Metals…”
