Note: Participants should bring their own laptop.
Numerical simulations are indispensable tools for building intuition and deepening understanding of complex ultrafast phenomena—offering a level of control, reproducibility, and insight that effectively complements cutting-edge experiments.
By exploring theoretical models interactively, researchers can test ideas, interpret experimental results, and design better experiments.
This hands-on session is designed to help participants understand some key concepts and use simulation tools in the field of strong-field and attosecond physics, with a focus on high-harmonic generation (HHG), using interactive Jupyter notebooks.
It is structured in three progressive parts:
(a) Ultrafast pulses – Explore how spectral width and phase derivatives affect pulse shape via inverse Fourier synthesis.Ultrafast pulses – Explore how spectral width and phase derivatives affect pulse shape via inverse Fourier synthesis.
(b) SAE model – Simulate HHG spectra of atoms like He, Ne, and Ar using the Lewenstein model.SAE model – Simulate HHG spectra of atoms like He, Ne, and Ar using the Lewenstein model.,
(c) TDDFT simulations – Run HHG calculations with Octopus and compare results with SAE model predictions and experimental data. Participants will be invited to explore parameters interactively and complete an extended TDDFT simulation as homework to better match experimental results.
