The PhD thesis by Carlos EcheverrÃa Arrondo, Doctor in Physics from the Public University of Navarre and entitled â€œOn doped semiconductor quantum dots and magnetic nanowiresâ€, studied the behaviour and properties of nanometric-scale semiconductor crystals.
The integration of single-spin magnetoelectronics into standard silicon technology may soon be possible.
Using powerful lasers, Hui Zhao, assistant professor of physics and astronomy at the University of Kansas, and graduate student Lalani Werake have discovered a new way to recognize currents of spinning electrons within a semiconductor.
Breakthrough paves way to store and process information in novel spin-electronics.
The best theory for explaining the subatomic world got its start in 1928 when theorist Paul Dirac combined quantum mechanics with special relativity to explain the behavior of the electron.
Experiment tests underpinnings of quantum field theory, Bose-Einstein statistics of photons.
For most people, frustration is a condition to be avoided - but for scientists studying certain "frustrated" ensembles of interacting components â€“ that is, those which cannot settle into a state that minimizes each interaction â€“ it may be the key to understanding a host of puzzling phenomena that affect systems from neural networks and social structures to protein folding and magnetism.
Though scientists argue that the emerging technology of spintronics may trump conventional electronics for building the next generation of faster, smaller, more efficient computers and high-tech devices, no one has actually seen the spinâ€”a quantum mechanical property of electronsâ€”in individual atoms until now.
There are enticing new findings this week in the worldwide search for materials that support fault-tolerant quantum computing.
NEW YORK, March 8 /PRNewswire/ -- SPIN, America's premier music resource, today announced the elements that will form the brand's 25th anniversary celebration.
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...
