Hi,
This is indeed an interesting feature. We do not currently have any plan to implement this within the WarpX team, but we would definitely support any external contributor that would like to take this on. :)
from warpx.
If you need any help with developing, debugging, testing this, do not hesitate to ask. I tried to describe the technical aspects as detailed as possible in https://doi.org/10.5281/zenodo.843510 - but in the end this is still more physics centered.

As an idea, @PrometheusPi's C++ implementation in PIConGPU is really compact, standalone and general:
https://github.com/ComputationalRadiationPhysics/picongpu/tree/master/include/picongpu/plugins/radiation
It includes to my knowledge the best practices for particle shapes and coherent/incoherent parts of the radiation as published in his papers: https://picongpu.readthedocs.io/en/0.6.0/usage/reference.html#diagnostic-methods
Would be great if we can reuse this work across multiple PIC codes?

I see, thank you all for your detailed replies. I was wondering, is the QED synchrotron emission implemented in WarpX?
I saw that in PIConGPU for instance that extension was removed via this PR.

@PrometheusPi Thanks a lot for the guidance! I think your concrete implementation is on top of your papers and your thesis well documented inline and could be adapted for reuse.
@berceanu is this something someone on your side would like to contribute here?
@PrometheusPi For curiosity, you are probably aware of this - I read through the above RaDiO paper from April 2023 and wonder if there is anything algorithmically new in it compared to your earlier works?
The only mention I find is
A key aspect of our algorithm is the development of a temporal interpolation scheme for depositing radiation. This is essential to preserve the continuous character of radiation emission and to obtain correct values for the amplitude of the radiated fields.
and wonder if that is also in your algorithm and/or worth adding?
