Discussion Overview

The discussion centers on whether subatomic particles, particularly electrons, can undergo phase changes similar to those observed in macroscopic materials. Participants explore concepts related to phase transitions, including the applicability of these ideas to subatomic systems and the nature of electron behavior in different states.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions if electrons can experience phase changes, suggesting analogies to liquid and gaseous currents.
  • Another participant argues that phase changes are meaningful only for macroscopic objects, asserting that a few molecules do not represent a gas, liquid, or solid in a significant way.
  • A different viewpoint suggests that the theory of phase transitions can apply to statistical systems of particles, including electrons, but not in the traditional gas, fluid, solid sense.
  • One participant introduces the concept of Cooper pairs in superconductivity as a known transition for electrons, while also mentioning theoretical considerations regarding magnetic monopoles.
  • Another participant questions the applicability of Ideal Gas laws to electrons in a DC current.
  • A response clarifies that electrons are better described as a Fermi gas, noting that the term "gas" in this context does not carry the same implications as in classical gas phases.
  • One participant provides a description of molecular behavior at higher energy levels, suggesting that increased energy leads to vibrations that can result in a gaseous state.

Areas of Agreement / Disagreement

Participants express differing views on the applicability of phase change concepts to subatomic particles, with no consensus reached on whether electrons can undergo phase changes analogous to those in macroscopic materials.

Contextual Notes

Participants highlight limitations in the definitions of phase changes and the significance of scale when discussing subatomic particles versus macroscopic systems. The discussion also reflects varying interpretations of theoretical frameworks.

Subatomic Phase changes?

Hi,

I was wondering if subatomic particles (electrons of example) experance phase changes. ie A liquid current or gaseous current of electrons.

Thanks...
 
Physics news on Phys.org
No sugestions?...
 
Can a water molecule have a phase change? No.

Only macroscopic objects can go through phase changes, a couple of molecules of water is not a gas, liquid or solid in any sort of meaningful sense similar to what we think of as gas liquid and solid.

A liquid current or gaseous current of electrons.

This is just a metaphorical use of the word current; gases and liquids don't exist on the scale of electrons.
 
The theory of phase transitions can certianly be applied to statistical systems of particles (electrons included),but not in the gas,fluid,solid,version.

in the case of electrons the best known transition would be the transition to Cooperpairs : ie superconductivity...

In theory, the same happens to mangetic monopoles...beware : this is theoretical physics.

What about electrons in a DC current. Can you not apply the Ideal Gas laws to them??
 
No,electrons are a typical example of Fermi gas...There are books written on Fermi gas.U'll need to understand though that the word "gas" is doesn't have the same significance as the when talking about the gas phase of most substances.

no the moelecules (when energy givin)

have more energy so with this energy it has no use for it so it uses it in vabration

so the moelecules vibrate more and pushes the moelecule further away
so it become a gas

thick of it you will get it
