High-energy heavy ion collisions can be a source of light flashes of a few yoctoseconds duration (a septillionth of a second, 10^-24 s) -- the time that light needs to traverse an atomic nucleus. This ...

Light pulses emitted by an exotic state of matter known as a quark–gluon plasma last for just a few yoctoseconds – according to calculations by physicists in Germany. One yoctosecond is one trillionth ...

Heavy ion collisions at CERN should be able to produce the shortest light pulses ever created, computer simulations demonstrate. The pulses are so short that they cannot even be measured by today's ...

Attoseconds are 10^-18 seconds. 1 attosecond is the time it takes for light to travel the length of three hydrogen atoms. Zeptoseconds are 10^-21 seconds Yoctoseconds are 10^-24 seconds. 1 ys: time ...

Scott Diddams and Tom O'Brian of the Time and Frequency Division of the National Institute of Standards and Technology, explain. Just how fast an event is depends somewhat on your point of view. In ...

For high-precision spectroscopy and structural studies of molecules, short light flashes with lowest possible wavelength, i.e., high photon energy, are required ...

Heavy ion collisions at CERN should be able to produce the shortest light pulses ever created. This was demonstrated by computer simulations at the Vienna University of Technology. The pulses are so ...
