Energy quantization in schrodinger equation

Click For Summary
SUMMARY

The discussion centers on energy quantization in the context of the time-independent Schrödinger equation, specifically the equation d²y/dx² = (2m/h²)(V-E)y, where V is a position-dependent potential and y is the eigenfunction. It is established that when the energy E exceeds the potential V, the eigenfunction y oscillates, indicating a continuous distribution of allowed energy values. The conversation highlights the distinction between quantum particles existing in superpositions of eigenstates and classical particles, emphasizing that energy eigenvalues cannot be directly compared to classical energy values unless the uncertainty in energy is negligible.

PREREQUISITES
  • Understanding of the Schrödinger equation and its components

USEFUL FOR

Students and professionals in physics, particularly those focusing on quantum mechanics, as well as educators seeking to deepen their understanding of energy quantization and its implications in both quantum and classical contexts.

in Schrödinger equation(time independent)

d^2y/dx2= 2m/h^2(V-E)y, V is a function of position coordinate, y is eigenfunction.
if E>V , y being -ve or +ve it would be a oscillatory function. The allowed energy values are continously distributed. Does this region correspond to classical regime of continuous energy values?
thnks for any rply.

The quantum particle you are describing will behave as a free quantum particle, however not necessarily as a classical particle, if that is what you are asking...?

A quantum particle doesn't exist in any particular eigenstate - it exists in a superposition of all eigenstates... Thus the idea of comparing energy eigenvalues to classical (absolute) energy values seems wrong.

If, however, the uncertainty in energy (as in the uncertainty principle) becomes negible, we can treat the energy of our particle as an absolute, and thus make an analogy to classical energy...
