Presentation Transcript

  1. PHY 741 – Quantum Mechanics 9-9:50 MWF Olin 107 Instructor: N. A. W. Holzwarth Room: Olin 300

  2. Today’s lecture • Introduction & announcements • Class organization • Reminder about Physics Colloquium at 3:45 in Olin 101; refreshments at 3:15 in Olin Lobby • Why Quantum Mechanics? • Introduction to Maple

  3. Why Quantum Mechanics (part 1) What does a practicing Quantum Mechanic do? Example: Modeling properties of materials

  4. LiPO3 Li2PO2N LiPO3 + Li3N  Li2PO2N + Li2O + 4.5 eV

  5. Why Quantum Mechanics (part 2) Classical Mechanics • r(t) – Trajectories of motion Quantum Mechanics • Probability amplitudes y(r,t) • <r>=∫d3r r|y(r,t)|2 • r == Hermitian operator
