Can't get material for smoke particle

I can have either emission or principled BSDF.  When I drag the position of the color ramp in cycles rendered mode, it seems to be trying to do something, but unless I overlap the markers nothing changes...  This is the same wether I use the provided material or if I create one myself.

    It looks like the result of the Divide is always 0, or at least really close to it. This means that the Lifetime of your Particles is  too long.
