SUMMARY

The smallest quantum of charge is not limited to 'e', the charge of an electron, as evidenced by the fractional quantum Hall effect. This phenomenon has demonstrated the existence of fractional charges, specifically in units of 1/3e and 1/5e, measured in two-dimensional semiconductor structures. The discussion highlights that while 'e' is a fundamental unit of charge, it is not the only charge that can exist in nature, as supported by three Nobel Prize-winning discoveries.

PREREQUISITES
  • Understanding of fundamental charge units, specifically 'e'
  • Knowledge of the fractional quantum Hall effect
  • Familiarity with two-dimensional semiconductor physics
  • Basic concepts of quantum mechanics
NEXT STEPS
  • Research the fractional quantum Hall effect and its implications on charge quantization
  • Study the properties of two-dimensional semiconductor structures
  • Explore the significance of Nobel Prize-winning discoveries in quantum physics
  • Learn about quarks and their fractional charges in particle physics
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the fundamental properties of charge and particle physics.

Hello all.

I was wondering - what is the smallest possible quantum of charge? Is it 'e', the charge on an electron? Then how are the charges on quarks explained? Am I right in thinking that the one quantum of charge is the smallest charge that can possibly exist?

"e" is the unit of charge. I'm not sure if you can consider it as a "quantum" of charge.

Is it the smallest charge that we have detected. Nope. 3 Nobel Prizes can point to that. Fractional quantum hall effect, and the resulting fractional charges, (in units of 1/3e and 1/5e) have been measured in 2D semiconductor structures.
