Are some elementary particles too massive to obey QM?

Click For Summary
SUMMARY

This discussion clarifies that all elementary particles, regardless of mass, adhere to the principles of quantum mechanics (QM). The key argument presented is that large mass does not inherently negate QM effects; rather, it is the number of degrees of freedom that leads to rapid decoherence, making quantum behaviors negligible. The conversation emphasizes that elementary particles, by definition, possess few degrees of freedom, thus they do not escape the probabilistic rules of QM. Therefore, massive elementary particles still conform to quantum principles, including wave-particle duality.

PREREQUISITES
  • Understanding of quantum mechanics principles, specifically wave-particle duality.
  • Familiarity with the concept of degrees of freedom in physics.
  • Knowledge of decoherence and its role in quantum mechanics.
  • Basic comprehension of elementary particles and their classifications.
NEXT STEPS
  • Research the implications of decoherence in quantum mechanics.
  • Study the characteristics and behaviors of elementary particles in quantum systems.
  • Explore advanced topics in quantum mechanics, focusing on wave-particle duality.
  • Investigate the relationship between mass and quantum behavior in composite versus elementary particles.
USEFUL FOR

This discussion is beneficial for physicists, students of quantum mechanics, and anyone interested in the fundamental behaviors of particles in quantum systems.

I understand photons and elections fit into the probalistic rules of QM. Are there any other elementary particles (more massive) that don’t obey the point/wave duality?
 
Physics news on Phys.org
A composite particle consisting of 810 atoms had been shown to produce interference pattern. If something that humongous shows QM behavior, do you think something significantly smaller than that such as "elementary particles", even more massive ones, would not?

Large mass by itself is not a reason to neglect QM effects. The QM effects are often negligible for large objects not because they have a large mass, but because they have a large number of degrees of freedom (i.e. consist of many elementary particles). Namely, larger number of degrees of freedom implies faster decoherence, which is why quantum effects become negligible very fast. On the other hand, you ask about massive elementary particles, and "elementary" implies that they do not have a large number of degrees of freedom. Hence the answer to your question is - no.
