I wonder if the lasers in Holmlids experiments are required to produce the rydberg matter, cause it to form UDD or initiate its "muon fusion" type behaviour?
I remember a while back Axil explained to me about how Rydberg Hydrogen matter forms in 2d crystals and in fact they can stack into threads. I wonder if Deuterium is used if this the same as UDD?
Could threads of Rydberg Matter like this resonate with particular frequencies and have a "thermal" phonon effect as has been discussed elsewhere? And would this have a characteristic frequency? Could the laser used by Holmlid excite this resonance at higher frequency compared to thermal resonance in this ultra dense material for example?
On a sperate point would Muonic deuterium be special in some way? The orbital muon would spend relatively more time in the nucleus when it does would there be a net charge impact in the nucleus. Could this also disturb significantly the coulomb barrier, and perhaps even perturb the nucleus.
