Well, finally with the help of my flatmate I figured it out. I post it just in case anybody else like me has this problem...
One has to solve the integral
\frac{1}{\Delta T} \int \frac{1}{2} \epsilon_{0} |E|^{2} d^{3}r
\Delta T is the duration time of the pulse, E the electric field...
Dear physicists,
I am desperate. I am using a QM code to propagate a wavefunction of a system that experienced an electric field pulse. However, in literature all values for the electric field strength are given in V/m but the program asks for W/cm^2! I am kind of very confused here and did not...
