Long predicted but never observed, coherent quantum phase slip can be harnessed to develop a novel class of quantum devices A new type of quantum bit called a "phase-slip qubit", devised by researchers at the RIKEN Advanced Science Institute and their collaborators, has enabled the world's first-ever experimental demonstration of coherent quantum phase slip (CQPS). The groundbreaking result sheds light on an elusive phenomenon whose existence, a natural outcome of the hundred-year-old...

International team that includes University of British Columbia physicists has used ultra-fast laser pulses to identify the microscopic interactions that drive high-temperature superconductivity An international team that includes University of British Columbia physicists has used ultra-fast laser pulses to identify the microscopic interactions that drive high-temperature superconductivity. In the experiment, to be outlined this Friday in the journal Science, electrons in a prototypical...

Previous world record shattered during 6-experiment pulse Researchers at Los Alamos National Laboratory's biggest magnet facility today met the grand challenge of producing magnetic fields in excess of 100 tesla while conducting six different experiments. The hundred-tesla level is roughly equivalent to 2 million times Earth's magnetic field. "This is our moon shot, we've worked toward this for a decade and a half," said Chuck Mielke, director of the Pulsed Field Facility at Los Alamos....

Scientists manufacture a cylinder which hides contents and makes them invisible to magnetic fields UAB researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using superconductor and ferromagnetic materials available on the market. The cylinder is built using high temperature superconductor material, easily refrigerated with liquid...

A team from the National Institute of Standards and Technology (NIST) and the University of Maryland has found an iron-based superconductor that operates at the highest known temperature for a material in its class. The discovery inches iron-based superconductors–valued for their ease of manufacturability and other properties–closer to being useful in many practical applications. Iron-based superconductors, which were discovered only about four years ago, are a hot research...

New Superconducting Materials Improve the Efficiency and Reliability of Grids and Systems For the first time, a superconducting current limiter based on YBCO strip conductors has now been installed at a power plant. At the Boxberg power plant of Vattenfall, the current limiter protects the grid for own consumption that is designed for 12 000 volts and 800 amperes against damage due to short circuits and voltage peaks. The new technology co-developed by Karlsruhe Institute of Technology and...

Study represents step toward unified theory for quantum phase transformation New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of several classes of materials -- including unconventional superconductors -- that have long vexed physicists. The findings in this week's issue of Nature Materials uphold a theory first offered in 2006 by physicist Qimiao Si, Rice's Harry C. and Olga K. Wiess Professor of Physics and...

University of Nottingham scientists have been levitating fruit flies with magnets to determine how biological organisms are affected by weightless conditions in space. The team has shown that simulating weightlessness in fruit flies on Earth by using magnets causes the flies to walk more quickly, which is a similar finding astronauts have had in experiments on the International Space Station. “It is unfeasible to apply this technique to investigating the effects of weightlessness...

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...
