Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.
Researchers have discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor.
In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce the exact location of a photoionization event.
Scientists have succeeded in performing time-resolved measurements of the internal energy distribution of stored clusters. The clusters investigated consisted of four cobalt atoms and an additional electron.
Quark-gluon plasma is formed as a result of high energy collisions of heavy ions. After a collision, for a dozen or so yoctoseconds, this most perfect of all known fluids undergoes rapid hydrodynamic expansion with velocities close to the velocity of light.
