SUMMARY

The first successful imaging of an electron has been achieved using an attosecond quantum stroboscope, which captures electron motion on a sub-femtosecond time scale. This technique employs a series of synchronized attosecond pulses alongside a guiding laser field, allowing for the detection of electron momentum distributions via a velocity map imaging spectrometer (VMIS). The discussion raises questions about the interpretation of the electron's appearance in the images, suggesting that the observed patterns may result from wave-like interference rather than depicting the electron's physical form. Overall, the findings contribute to the understanding of electron behavior in quantum mechanics.

PREREQUISITES
  • Understanding of quantum mechanics principles

"Electron photographed for the first time"

An electron rides on a light wave after just having been pulled away from an atom.

Is somebody certain of where and what exactly was THAT which created that blue shape on the picture? I mean, a guess of mine is: THAT is the thick part of a cylidrical longitudinal wave (ray) which is the laser-like "electron beam", and has a diametre equal to the diametre of the ray. Exactly as a sound wave has thick and sparse areas of molecules. More exactly, like the thick part a ultrasound laser-like ray. How much correct is my guess? Check this out too:

Nobody knows what the electron is?

I'll take the time to look at the vids, but I can offer this for now:
An electron is an electron is an electron.

It's a fundamental particle(not made up of other smaller particles)

I'm not understanding what the video is showing. Is that whole thing the electron, or is the electron somewhere in the circles and stuf? If the whole thing is the electron, I'm guessing that it looks the way it does because of wavelike interference and such?
 


Yeah, I agree.
Not much to go on here.
 


does it say how big it is?

Here we demonstrate an attosecond quantum stroboscope capable of guiding and imaging electron motion on a sub-femtosecond (1 fs = 10-15 s) time scale. It is based on a sequence of identical attosecond pulses6 which are synchronized with a guiding laser field. The pulse to pulse separation in the train is tailored to exactly match an optical cycle of the laser field and the electron momentum distributions are detected with a velocity map imaging spectrometer (VMIS)7,8.

Pioneering experiments with femtosecond infrared (IR) laser fields have demonstrated that temporally localized electron wave packets (EWPs) can be used to study molecular structures and dynamics
 


So that whole thing is the electron then right? Or the momentum distributions of it or whatever?
