Coherent electrons in double slit experiment?

Click For Summary

Discussion Overview

The discussion revolves around the coherence of electrons in the context of the double slit experiment. Participants explore the requirements for ensuring that ejected electrons are coherent and the implications of coherence on the production of interference patterns.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant questions how coherence of ejected electrons can be experimentally ensured.
  • Another participant suggests that coherence is primarily a requirement for light beams, implying a distinction between light and electrons.
  • A different participant challenges this view, stating that incoherent electrons would not be able to produce an interference pattern.
  • One participant expresses ongoing confusion about the problem, indicating that the topic remains complex and unclear.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are competing views regarding the necessity of coherence for electrons and its implications for interference patterns.

Experimentally how do we make sure that the ejected electrons are coherent?

I think it is mainly required for light beams.
 
Why? I don't think incoherent electrons can produce a interference pattern

Hmm I was just thinking about this problem again, still confusing...
