Is the given 1-D potential an example of a bound state?

Click For Summary
SUMMARY

The discussion centers on the classification of a 1-D potential with an infinite barrier at x<0 and zero potential for x>0. The consensus is that this scenario does not represent a bound state, as the wavefunction oscillates to infinity and cannot be normalized. According to established definitions, a bound state requires the wavefunction to approach zero as x approaches both positive and negative infinity, which is not satisfied in this case.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly wavefunctions
  • Familiarity with the concept of bound and unbound states
  • Knowledge of normalization conditions for wavefunctions
  • Basic grasp of potential energy in quantum systems
NEXT STEPS
  • Study the properties of wavefunctions in quantum mechanics
  • Explore the definitions and characteristics of bound states in quantum systems
  • Learn about normalization techniques for wavefunctions
  • Investigate the implications of infinite potential barriers in quantum mechanics
USEFUL FOR

Students and professionals in physics, particularly those focusing on quantum mechanics, wavefunction analysis, and potential energy concepts.

In 1-D if I have an infinite potential at x<0 so the wavefunction is zero for x<0 but for x>0 the potential is zero so the wavefunction oscillates to infinity is that a bound state ? I presume this isn't bound as it can't be normalized but most definitions state that bound means the wavefunction tends to zero as x tends to + or - infinity. so is my example bound ? Thanks

No, its not bound because it can radiate to infinity. See here!
