    Photon Spacetime
AI Thread Summary
The discussion explores how a low-energy photon affects spacetime, questioning whether its gravitational influence follows the wave's shape as it travels. It highlights the absence of a quantum theory of gravity, suggesting that examining classical light pulses through pp-wave spacetimes may provide insights. The conversation references various resources, including links to illustrations of plane waves and gravitational waves for better understanding. The complexity of visualizing a photon's impact on spacetime is acknowledged, emphasizing the need for further exploration in this area. Overall, the topic remains open-ended, inviting deeper investigation into the relationship between photons and spacetime distortion.

Lets say I have a very low energy photon moving through space and I want to visualize how space-time is effected by the motion of the photon thru space.

Photons are supposed to be quantized.. If it were possible to build a machine to measure the "gravitational" effect of a single photon would it follow the shape of the wave at each point as it traveled thru space? Would it deform the whole region of the packet? What would it look like if you drew it out?

We don't have a quantum theory of gravity yet. However, if you are willing to discuss classical pulses of light instead of photons then you should look into pp-wave spacetimes.
 
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...
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...
