Is the Uncertainty Principle the Key to Solving Homework Problems?

Click For Summary
SUMMARY

The discussion centers on the application of the Uncertainty Principle in quantum mechanics to solve specific homework problems involving commutators. The user queries whether the commutators [p, V(x)] and [x, H] yield affirmative answers to their homework questions. They assert that the commutator [p, V(x)] results in -ih/2π (∂V/∂x), leading to the conclusion that the Uncertainty Principle applies to observables with commutators equal to ±ih/2π. This indicates a clear understanding of the relationship between commutators and the Uncertainty Principle.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with commutators in quantum theory
  • Knowledge of the Uncertainty Principle
  • Ability to perform partial differentiation
NEXT STEPS
  • Study the implications of the Uncertainty Principle in quantum mechanics
  • Learn about the mathematical properties of commutators
  • Explore examples of observables with non-zero commutators
  • Investigate the role of partial derivatives in quantum mechanics
USEFUL FOR

Students and educators in physics, particularly those focusing on quantum mechanics, as well as anyone seeking to deepen their understanding of the Uncertainty Principle and its mathematical foundations.

The Attempt at a Solution



Am i right in thinking that the answer to both questions is yes? Neither of the commutators [p, V(x)] nor [x, H = + or - ih..

therefore is the answer to both a and b yes?

The thing is that [p, V(x)] gives -ih/2pi DV/DX where D/Dx is partial d/dx..

does the uncertainty principle only hold between oberservables whose commutator = plus or minus ih /2pi?

Thanks
 
Can anyone help with this?
