HHG from strong field approximation theory

Usage

Simply make, then ./test or python run.py

Core function

void calc_hhg(long nt, double dt, double* Ef, double* dout)

requires nt, the size of the time grid, dt, the time step size, Ef, the grid storing electric field and dout, the real part of $d(t)$

Files

• libhhg.cc: the source file that builds a tiny library file libhhg.so providing the interface function calc_hhg. See main.cc to see how to call calc_hhg.

• run.py: a simple python script invoking libhhg.so, can easily manipulate parameters and call calc_hhg function to generate dipole(t)

• main_full.cc: an indepedent file to calculate HHG for H1s with the SFA model
