Protons, Photons, and ionic states of matter with one type

AI Thread Summary
Imparting heat to a cloud of protons via electromagnetic radiation is challenging, as photons primarily interact with electrons rather than protons. The concept of forming a liquid state of matter, like a "proton soup," raises questions about the behavior of protons and other ions under extreme conditions. At very low or high temperatures, the repulsive forces between charged particles could potentially be overcome, leading to the possibility of creating a proton superfluid in a laboratory setting. The Large Hadron Collider may provide insights into these interactions and the conditions required for such states of matter. Understanding these phenomena could significantly advance knowledge in particle physics and state formation.

Is it possible to impart heat to a cloud of protons via EM radiation? Photons usually interact with electrons, and I can't find much info on pure photon-proton interaction.

Also, if you took some hydrogen ions (protons, to be specific), could you form a state of matter, such as a liquid proton soup? What about with other ions, say Na+, or O2-?

I understand that normally, the charges would repel each other, but what about at extremely low or high temperatures? Could you prepare a proton superfluid in a lab, for example? What conditions would be necessary and what properties would they exhibit?

Look at the large hadron collider. I believe it will go a long way to answering your questions.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
