We learn it at high school: Release two objects of different masses in the absence of friction forces and they fall down at the same rate in Earth's gravity. What we haven't learned, because it hasn't been directly measured ...
Russian physicists have developed a method for drastically narrowing the emission spectrum of an ordinary diode laser, like that in a laser pointer. This makes their device a useful replacement for the more complex and expensive ...
A transistor based on the 2-D material tungsten ditelluride (WTe2) sandwiched between boron nitride can switch between two different electronic states—one that conducts current only along its edges, making it a topological ...
Â鶹ÒùÔºicists from the University of California, Irvine have discovered a new way to control magnets at the nanometer scale by electric current. This breakthrough, detailed in a paper published today in Nature Nanotechnology, ...
Scientists at the Max Planck Institute Chemical Â鶹ÒùÔºics of Solids have written a review paper about magnetic topological materials in the family of Heusler compounds. The review explains the connection between topology, symmetry ...
In a refreshing change of perspective, theoretical physicist Dr. Zeila Zanolli has looked at the proximity effects of graphene on a magnetic semiconducting substrate, finding it to affect the substrate's magnetism down to ...
With their current approach, energy companies can extract about 35 percent of the oil in each well. Every 1 percent above that, compounded across thousands of wells, can mean billions of dollars in additional revenue for ...
In pursuit of numerical predictions for exotic particles, researchers are simulating atom-building quark and gluon particles over 70 times faster on Summit, the world's most powerful scientific supercomputer, than on its ...
Quantum particles can be difficult to characterize, and almost impossible to control if they strongly interact with each other—until now.
A new technique makes it possible to obtain an individual fingerprint of the current-carrying edge states occurring in novel materials such as topological insulators or 2-D materials. Â鶹ÒùÔºicists of the University of Basel ...
