By Jennifer Marcus, UCLA Physicists at UCLA set out to design a better transistor and ended up discovering a new way to think about the structure of space. Space is usually considered infinitely divisible "” given any two positions, there is always a position halfway between. But in a recent study aimed at developing ultra-fast transistors using graphene, researchers from the UCLA Department of Physics and Astronomy and the California NanoSystems Institute show that dividing space into...

The goal: Room-temperature spintronic computers University of Utah researchers built "spintronic" transistors and used them to align the magnetic "spins" of electrons for a record period of time in silicon chips at room temperature. The study is a step toward computers, phones and other spintronic devices that are faster and use less energy than their electronic counterparts. "Electronic devices mostly use the charge of the electrons - a negative charge that is moving," says Ashutosh Tiwari,...

Technique suggests an avenue for creating new kinds of superconductivity Physicists at the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park, have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to...

The fabric of space-time around spinning black holes should impart a "twist" in the property of light called orbital angular momentum. This momentum which could be detected here on Earth, the researchers say, may provide the first unique signature of black holes, reports the journal Nature Physics. Light particles , or photons, carry two kinds of momentum but only one of them is familiar. "If we take the Earth as an example, it spins around its own axis in about 24 hours - that is its spin...

A team of physicists has taken a big step toward the development of useful graphene spintronic devices. The physicists, from the City University of Hong Kong and the University of Science and Technology of China, present their findings in the American Institute of Physics' Applied Physics Letters. Graphene, a two-dimensional crystalline form of carbon, is being touted as a sort of "Holy Grail" of materials. It boasts properties such as a breaking strength 200 times greater than steel and, of...

A new scientific discovery could have profound implications for nanoelectronic components.  Researchers from the Nano-Science Center at the Niels Bohr Institute, University of Copenhagen, in collaboration with Japanese researchers, have shown how electrons on thin tubes of graphite exhibit a unique interaction between their motion and their attached magnetic field "“ the so-called spin. The discovery paves the way for unprecedented control over the spin of electrons and may have a...

An international team of researchers featuring Texas A&M University physicist Jairo Sinova has announced a breakthrough that gives a new spin to semiconductor nanoelectronics and the world of information technology. The team has developed an electrically controllable device whose functionality is based on an electron's spin. Their results, the culmination of a 20-year scientific quest involving many international researchers and groups, are published in the current issue of Science. The...

Scientists from the Kavli Institute of Nanoscience at Delft University of Technology and Eindhoven University of Technology have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now able to manipulate these building blocks (qubits) with electrical rather than magnetic fields, as has been the common practice up till now. They have also been able to embed these qubits into semiconductor nanowires. The scientists' findings have been published in the...

Researchers pave the way for spin computers A research team from the Institut Català de Nanotecnologia (ICN), in Barcelona, has demonstrated a device that induces electron spin motion without net electric currents, a key step in developing the spin computers of the future. The results are published in the Dec 17 issue of the journal Science. The authors are Marius V. Costache and Sergio O. Valenzuela, an ICREA Professor who is leader of the Physics and Engineering of...

A gyroscope uses the principles of conservation and angular momentum to measure and maintain orientation. The mechanical gyroscope is a spinning wheel or disk whose axle is free to take any orientation. The gyroscope's high rate of spin allows for large angular momentum which makes the orientation changes much more responsive to a given external torque. There is also the electronic, microchip-packaged MEMS gyroscope, solid state ring laser and fiber optic gyroscope, as well as the extremely...

Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
