Time Delay in Photoemission by Attosecond Laser Pulses
J. Marciak-Kozlowska and M. Kozlowski
Recently the time delay in the attosecond photoemission was observed. In this paper we propose the description of that time delay in the framework of the hyperbolic heat transport equation. We argue that the observed time delay of around 20 attoseconds is of the order of the thermal relaxation time for hyperbolic quantum heat transport. As the generalization of the standard quantum mechanics we propose the new local Schrödinger equation with c ≠ ∞ for attodynamics.
