Yoctosecond photon pulses from quark-gluon plasmas

Understand

Present ultra-fast laser optics is at the frontier between atto- and zeptosecond photon pulses, giving rise to unprecedented applications.

• We show that high-energetic photon pulses down to the yoctosecond timescale can be produced in heavy ion collisions.
• We focus on photons produced during the initial phase of the expanding quark-gluon plasma.
• We study how the time evolution and properties of the plasma may influence the duration and shape of the photon pulse.
