Modular multiscale approach (MMA) to modelling high-harmonic generation in gases
Description
We present a modular user-oriented simulation toolbox for studying high-harmonic generation in gases [1]. The first release consists of the computational pipeline to 1) compute the unidirectional IR-pulse propagation in cylindrical symmetry, 2) solve the microscopic responses in the whole macroscopic volume using a 1D-TDSE solver, 3) obtain the far-field harmonic field using a diffraction-integral approach. The code comes with interfaces and tutorials, based on practical laboratory conditions, to facilitate the usage and deployment of the code both locally and in HPC-clusters. The interfaces also provide extendability of the code. Additionally, the modules are designed to work as stand-alone applications as well, e.g., 1D-TDSE is available through a Pythonic interface.
