US-European team revisits 30-year-old breakthrough with new methods, understanding European and U.S. physicists this week are offering up the strongest evidence yet that magnetism is the driving force behind unconventional superconductivity. The findings by researchers from Rice University, the Max Planck Institute for Chemical Physics of Solids (MPI-CPfS) in Dresden, Germany, and other institutions were published online today in Nature Physics. The findings follow more than three decades of...

Tracking down Cooper pairs: RUB researchers confirm theoretical hypothesis The results achieved by this research team headed by Prof. Kurt Westerholt and Prof. Hartmut Zabel (Department of Physics and Astronomy at RUB) could contribute to new, power saving components in the future. The researchers reported on their findings in the American Physical Society's noted journal "The Physical Review". Electron pairs in singlet state If it were possible to eliminate electrical resistance we could...

Scientists can use cylinders as small as teapots to study the mechanisms involved in powerful hurricanes and other swirling natural phenomena. The earth's atmosphere and its molten outer core have one thing in common: Both contain powerful, swirling vortices. While in the atmosphere these vortices include cyclones and hurricanes, in the outer core they are essential for the formation of the earth's magnetic field. These phenomena in earth's interior and its atmosphere are both governed by the...

A new material with a split personality -- part superconductor, part metal -- has been observed by a Princeton University-led research team. The discovery may have implications for the development of next-generation electronics that could transform the way information is stored and processed. The new material -- a crystal called a topological superconductor -- has two electronic identities at once. At very low temperatures, the interior of the crystal behaves like a normal superconductor,...

Extending its 26-year tradition of innovative quantum voltage standards, researchers at the National Institute of Standards and Technology (NIST) have begun shipping a new 10-volt standard to users around the world. The programmable system measures both direct current (DC) and alternating current (AC) voltages. NIST AC/DC 10-volt standard chip. The new 10-volt system* builds on a number of previous NIST inventions, from the initial 1-volt standard in 1984 through the 2006 unveiling of the...

Atoms are proxies for electrons in ultracold optical emulator A Rice University-led team of physicists is reporting the first success in a three-year effort to build a precision simulator for superconductors using a grid of intersecting laser beams and ultracold atomic gas. The research appears this week in the journal Nature. Using lithium atoms cooled to within a few billionths of a degree of absolute zero and loaded into optical tubes, the researchers created a precise analog of a...

HZB-Scientists discovered a unique feature of Superconductivity Since their discovery in 2008, a new class of superconductors has precipitated a flood of research the world over. Unlike the previously familiar copper ceramics (cuprates), the basic structure of this new class consists of iron compounds. Because the structure of these compounds differs from the cuprates in many fundamental ways, there is hope of gaining new insights into how the phenomenon of superconductivity arises. In...

Measurements taken* at the National Institute of Standards and Technology (NIST) may help physicists develop a clearer understanding of high-temperature superconductors, whose behavior remains in many ways mysterious decades after their discovery. A new copper-based compound exhibits properties never before seen in a superconductor and could be a step toward solving part of the mystery. Copper-based high-temperature superconductors are created by taking a nonconducting material called a Mott...

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
