2.2 Postulates of Quantum Mechanics (Verified standard set)

  1. State: Wavefunction ( \Psi(\mathbfr, t) ) contains all information; ( \int |\Psi|^2 d\tau = 1 ).
  2. Observables: Represented by Hermitian operators.
  3. Measurement: Result is eigenvalue of corresponding operator; probability given by ( |c_n|^2 ) in expansion ( \Psi = \sum c_n \psi_n ).
  4. Time evolution: Schrödinger equation ( i\hbar \frac\partial \Psi\partial t = \hatH \Psi ).
  5. Collapse: Upon measurement, ( \Psi ) collapses to eigenstate of measured observable.

  • Potential: ( V(r) = -\frace^24\pi\epsilon_0 r ) (Coulomb).
  • Schrödinger equation in spherical coordinates: Separable: ( \psi_nlm(r,\theta,\phi) = R_nl(r) Y_l^m(\theta,\phi) ).
  • Quantum numbers:

    The search results were a chaotic bazaar of academia. There were broken links from defunct GeoCities pages, predatory sites promising "FREE PDFS" (likely laden with malware), and dense papers from the 1970s. But near the top, sitting with an air of quiet authority, was a result tagged simply as "Verified." State: Wavefunction ( \Psi(\mathbfr, t) ) contains all

  • Roothaan-Hall equations: ( \mathbfF \mathbfC = \mathbfS \mathbfC \mathbfE ) (matrix form using basis functions).
  • Limitation: Neglects electron correlation.
