Optical laser matter interaction

A very quick literature survey on the topic of optical laser-matter interaction (fs laser, nanoparticles)

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9105410/

• NPs in liquid interacting with optical laser
• only long pulse lasers
• two-temperature MD model
• no code

http://dx.doi.org/10.34726/hss.2014.26362

• Dissertation thesis Georg Wachter
• Simulation of condensed matter dynamics in strong femtosecond laser pulses
• TDDFT method
• no code

https://octopus-code.org/new-site/main/tutorial/

• octupus: realtime realspace TDDFT
• not sure if MD is included
• Can run octopus in ASE and then run MD also in ASE

https://iopscience.iop.org/article/10.1088/1361-6455/aa69e6/

• Phae Ho (ANL)
• HF Slater one-electron model
• x-ray laser matter interaction (not optical laser)
• they combine their HFS simulation with LAMMPS to model the ionic expansion, maybe this can also be done with fs OL simulations

General thoughts

Since there are at least 3 orders of magnitude between the OL pulse duration (~fs) and the pump-probe delay (ps-ns), it is questionable if we really need a fine grained understanding of the laser matter interactios as delivered by e.g. TDDFT. We may get away with a rough scaling law of energy absorption and ionization as function of laser energy and pulse duration and then perform a classical MD simulation for the evolution of the particle after the pulse.
