Superconductivity is a complete loss of electrical resistance. Superconductors are not merely very good metals: it is a fundamentally different electronic state. In normal metals, electrons move individually, and they collide with defects and vibrations in the lattice. In superconductors, electrons are bound together by an attractive force, which allows […]

AQFP MANA microprocessor die photo. MANA is the world’s first adiabatic superconductor microprocessor. Credit: Yokohama National University Researchers from Yokohama National University in Japan have developed a prototype microprocessor using superconductor devices that are about 80 times more energy efficient than the state-of-the-art semiconductor devices found in the microprocessors of […]

In their research, the researchers also demonstrated the peculiarity of a new type of “Bad metals,” called “Hund’s metals,” important for a class of iron-based materials. Scientists believe that these materials are particularly interesting because they are superconductive and rather malleable, which makes them highly suited to technological applications. Credit: […]

The goal of new research led by Ranga Dias, assistant professor of mechanical engineering and of physics and astronomy, is to develop superconducting materials at room temperatures. Currently, extreme cold is required to achieve superconductivity, as demonstrated in this photo from Dias’s lab, in which a magnet floats above a […]

This illustration shows a crystal lattice of strontium ruthenate responding to various sound waves sent via resonant ultrasound spectroscopy as the material cools through its superconducting transition at 1.4 kelvin (minus 457 degrees Fahrenheit). The highlighted deformation suggests the material may be a new type of superconductor. Credit: Courtesy of […]

Injecting calcium into graphene creates a superconductor, but where does the calcium actually end up? Credit: FLEET ‘Floating’ Graphene on a Bed of Calcium Atoms Adding calcium to graphene creates an extremely-promising superconductor, but where does the calcium go? Adding calcium to a composite graphene-substrate structure creates a high transition-temperature (Tc) superconductor. […]

Credit: Maximilien Brice/CERN Over the past thirty years, the exploration of the infinitely small has gone hand-in-hand with advances in superconducting magnets. The increasingly powerful hadron colliders, from the Tevatron, commissioned in 1983, to the LHC in 2008, have led […]

Deciphering previously invisible dynamics in superconductors — Higgs spectroscopy could make this possible: Using cuprates, a high-temperature superconductor, as an example, an international team of researchers has been able to demonstrate the potential of the new measurement method. By applying a strong terahertz pulse (frequency ω), they stimulated and continuously […]
