(Phys.org)—A team of researchers working at the University of Konstanz, in Germany is claiming to have directly sampled electric-field vacuum fluctuations, which would be the first ever made. In their paper published in ...
(Phys.org)—It was an impressive week for researchers combining physics and engineering as one team of engineers took a big step toward using light instead of wires inside computers—they've created a prism-like device ...
By solving a six-dimensional equation that had previously stymied researchers, University of Nebraska-Lincoln physicists have pinpointed the characteristics of a laser pulse that yields electron behavior they can predict ...
