Implement Compton scattering as a new binary process

We could use linear Breit-Wheeler as a template: https://github.com/BLAST-WarpX/warpx/pull/3630

WarpX spends a lot of time in EB initialization

Yes, thank you!

Python: `elements.survey(lattice)`

Could we add a plot of the beamline, similar to the one at the bottom of this page: https://cheetah-accelerator.readthedocs.io/en/latest/examples/simple.html

Capillary discharge

Thanks for the question. I think that the answer depends on exactly which physical processes you would like to capture in these simulations, and over which timescales. Do you know...

[WIP] ablastr: add functions to perform conversions between SI units and Natural units

I flagged this PR as [WIP] while we wait for #5828 to be merged.

Performance of `CurlCurlMLMGPC` on GPUs

In case this is useful, here is some documentation on how to profile the WarpX with Nsight system: https://warpx.readthedocs.io/en/latest/developers/how_to_profile.html#nvidia-nsight-systems (e.g. on a single GPU already)

Inquiry on FBPIC Multi-GPU Parallel Acceleration Failure

Thanks for this question @kelly1122i. Indeed it is entirely possible that FBPIC simulations may not see significant speed up from multi-GPU setups, because of the overheads involved in the communicating...

NaN values encountered when trying to setup user-defined auxiliary variables

Great, thanks a lot! Let me know if there is any additional test I can to do to help.

NaN values encountered when trying to setup user-defined auxiliary variables

Thanks for the input @zingale Could you point me to the code where Castro computes the pdV term from the Godunov state?

what about fbpic data type during running？

Thanks for the question and sorry for the late reply. FBPIC uses double-precision floating-point representation everywhere (i.e. `double` in the C/C++ nomenclature). In the context of Python, the type `float`...
