Thank you very much!
I'm sorry for my mistake that omega
has the dimension of inverse time Hertz
beause of omega=c*k[SpeedOfLight multiply VectorNumber]
right now ,I want define [Mu] as a variable with dimension of ElectronVolt.
I can't get it in my computer's mathmatica as following code : [Mu]=QuantityVariable[[Mu],"ElectronVolt"]
how to rectity my falut to get my purpose to plot [Sigma] vs diffrent [Mu] ranging from 0 eV to 0.5 eV.
farther more.
I want plot sigma with variable [Mu] ranging from 0eV(ElectronVolts) to 0.5eV;[Lamda] ranging from 1400nm to 1600nm ,which changes the values of [Omega]. and parameters [tau] ranging from 0.1ps[picoseconds] to 0.5ps.
Would you please help me to rectify my fault .Thanks!
