Large number of photons occupy the same quantum mechanical state?

Click For Summary

Homework Help Overview

The discussion revolves around the possibility of creating a device that produces a beam of electrons similar to how lasers produce a beam of light with many photons occupying the same quantum mechanical state. The subject area includes quantum mechanics, specifically the behavior of bosons and fermions.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the differences between photons and electrons, particularly in relation to their classifications as bosons and fermions, and the implications of the Pauli exclusion principle on their ability to occupy the same state.

Discussion Status

Some participants have provided clarifications regarding the nature of bosons and fermions, and the original poster has expressed appreciation for the guidance received. There appears to be an ongoing exploration of the concepts involved, with no explicit consensus reached yet.

Contextual Notes

Participants are encouraged to look up additional information on the Pauli exclusion principle and the distinctions between bosons and fermions to further their understanding of the topic.

Homework Statement


Lasers produce a beam of light in which a large number of photons occupy
the same quantum mechanical state. Is it possible to build a similar device
producing such a beam of electrons? Explain.


Can anyone help? I don't know on which concept should I base this. I just need a starting point. Thanks

Wikipediate bosons and fermions. Which are photons? Which are electrons?
 
Thanks for the reply.

Great! I just started reading that.

Photons -> bosons -> they can occupy same state
Electrons -> fermions -> they can't occupy the same statebecause they are truly indistinguishable according to the Exclusion Principle -> thus we can't design the device

How does that sound?

Good- but both fermions and bosons are truly indistinguishable. You should also Wikipediate 'Pauli exclusion principle'.
 
Alright .. thanks a lot .. that really helped :)
