Landslides are one striking example of erosion. When the bonds that hold particles of dirt and rock together are overwhelmed by a force—often in the form of water—sufficient to pull the rock and soil ...
Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...
A new kind of laser uses tiny moving particles to produce beams of light. The laser is more programmable than standard lasers and the approach could be used to create visual displays that are sharp ...
