FAQs on Lecture 2: Non Degenerate Perturbation Particle in Box Video Lecture - Quantum Mechanics for GATE - GATE Physics

1. What is non-degenerate perturbation in quantum mechanics?
Ans. Non-degenerate perturbation in quantum mechanics refers to a situation where the perturbing Hamiltonian does not cause any degeneracy in the energy levels of the system.
2. How does perturbation theory apply to a particle in a box system?
Ans. Perturbation theory can be used to analyze the effects of small changes in the potential energy on the wave function and energy levels of a particle in a box system.
3. What are the key differences between degenerate and non-degenerate perturbation theory?
Ans. Degenerate perturbation theory is used when there are degeneracies in the energy levels of the system, while non-degenerate perturbation theory is applied when there are no degeneracies present.
4. How does the perturbation affect the energy levels and wave functions of a particle in a box system?
Ans. The perturbation causes the energy levels to shift and the wave functions to be modified, resulting in a new set of energy levels and wave functions for the system.
5. Can non-degenerate perturbation theory be applied to systems other than a particle in a box?
Ans. Yes, non-degenerate perturbation theory can be applied to a wide range of quantum mechanical systems where small changes in the potential energy can be analyzed to determine the effects on the system's energy levels and wave functions.
