Utils for ultrafast spectroscopy: pump pulse generation.

Functions

delta_occs_pulse_coef	Additional occupation due to the pulse excitation.
gaussian	Gaussian function normalized to unity max occupation
gaussian_excitation	The Gaussian pulse excitation for the Perturbo dynamics.
setup_pump_pulse	Setup the Gaussian pump pulse excitation for electrons and holes.
sigma_from_fwhm	Comupte Gaussian sigma from the Full Width at Half Maximum (FWHM) parameter: .. math:: f(t) = A / ( sigma * sqrt(2pi)) exp(-(t-t0)^2 / (2sigma^2)).
