Unformatted text preview: Quantum mechanics is the description of the behavior of matter and light in all its details and, in particular, of the happenings on an atomic scale. Things on a very small scale behave like nothing that you have any direct experience about. They do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen.--Richard P. Feynman Introduction to Quantum Mechanics This week and the next are critical for the course Week 3 Lect. 5,6: Light as Particles -- Particles as waves -- Wave-Particle Duality -- Probability --Uncertainty Principle -- Weirdness of Quantum Mechanics Week 4 Lect. 7,8: Schrdinger Equation -- Definite predictions of quantum behavior -- Examples of particles in infinite wells, finite wells -- Leads up to rest of course Midterm Exam Monday, Feb. 11 - will cover Lectures 1-7 and qualitative aspects of lecture 8 Week 4 The discussion and the quiz will be on material in lecture 7 Week 4 Online homework covers material in lecture 7 due on Thur. Feb. 14, but we strongly encourage you to look at the homework before the midterm!

Review Sunday, Feb. 10 - office hours Feb. 10 and 11 Introduction to Quantum Physics: Matter Waves de Broglies proposal and the Schrdinger Equation Overview Overview c Wave nature of particles c Proposed by DeBroglie in 1923 c Demonstrated by diffraction from crystals just like X-rays! c Matter-wave Interference c Double-slit interference pattern just like photons c Electron microscopy c Heisenberg Uncertainty Principle c Cannot measure position and velocity of a particle simultaneously c Implications for measurements in QM c Schrdinger Equation (SEQ) c Time-dependent SEQ replaces F=ma (follow-up later) c Time-independent SEQ gives static solutions for wavefunctions c Physical interpretation of the wavefunction Matter Waves Matter Waves c Prince Louis de Broglie (1923) proposed that particles also behave as waves; i.e., for all particles there is a quantum wave with frequency and wavelength given by...
