Study Notes
Quantum Mechanics: One Dimensional Simple Harmonic Oscillator
- The simple harmonic oscillator moves under a restoring force that tries to restore it to the equilibrium position.
- The energy of a simple harmonic oscillator is quantized or discrete, which is represented by equation (25).
- The energy eigenvalues are given by equation (25).
Differences between Classical Mechanics and Quantum Mechanics
- In classical mechanics, the energy of a simple harmonic oscillator is continuous, whereas in quantum mechanics, it is quantized or discrete.
- The harmonic oscillator's behavior is fundamentally different in classical mechanics and quantum mechanics.
Mathematical Derivations
- Equation (12) can be rewritten as +𝛃𝟐 𝟐 𝛙 = 𝐜𝐨𝐧𝐬𝐭.𝐞 −𝛃𝟐 𝟐 + 𝐜𝐨𝐧𝐬𝐭.
- Substituting equations (16), (19), and (20) into equation (15) yields: ∞ (𝐧 + 𝟐)(𝐧 + 𝟏)𝐀𝐧+𝟐 − 𝟐𝐧 + 𝟏 − 𝛂 𝐀𝐧 𝛃𝐧 = 𝟎 𝐧=𝟎
- Solving for 𝐀𝐧+𝟐, we get: 𝐀𝐧+𝟐 = 𝟎
- This leads to: 𝟐𝐧 + 𝟏 − 𝛂 = 𝟎
- Consequently, 𝛂 = 𝟐𝐧 + 𝟏
