| Outline of Research at the Start |
This research aims at developing a new theoretical model for simulating strong field ionization and post-ionization excitation with general application, which includes optical coupling before ionization, affect from multi-electron interaction during ionization and the excitation process in ions.
|
| Outline of Annual Research Achievements |
Based on the results of the simulations performed in the past academic year, the ionization timing issue is further investigated, so that all the ionization processes induced throughout the entire laser pulse can be included.
Secondly, we developed quantum algorithms for simulating the post-ionization excitation process using the sudden turn-on model on a quantum computer. Both simulator testing and real machine IBM-Q and continuum testing are done.
Thirdly, by taking advantage of the theoretical methods I developed in the past fiscal year on the ionization and excitation of molecular systems, I investigated theoretically how molecules are ionized and excited by an attosecond laser pulse whose wavelength is in the extreme ultraviolet region.
