  1. SP425 Quantum Mechanics II with Advanced Laboratory II

  2. QM Courses • SP327 Modern • relativity • old quantum theory • QM overview • SP324 Quantum I with Advanced Lab I • QM formalism with strange math • SP425 Quantum II with Advanced Lab II • What do you do if ... ? (aka perturbation theory) • QM Applications survey • Hydrogen atom • multielectron atoms • molecules • nuclear • solid state • elementary particles • quantum statistics

  3. Recommended Resources • Eisberg & Resnick • std junior year physics book, but... • http://hyperphysics.phy-astr.gsu.edu/hbase/quacon.html#quacon • ...do some surfing.... • Griffiths “Intro to QM” • available in lab • Melissinos “Experiments in Mod Phys” • available in lab

  4. SP425 Short Syllabus • Uncertainty Analysis • SP324 Review • Perturbation Theory – how to correct oversimplified calcs • Time-dep Perturb Theory – how to calculate decay rates • Corrections to the simplified hydrogen atom from last semester • Multi-electron Atoms • Molecules • Quantum Statistics (preview to SP444: Stat Mech) • Nuclear • Solid State / Condensed Matter / Superconductivity / SQUIDS • Elementary Particles • Relativisitic Quantum Mechanics: Dirac Equation

  5. SP425 Lab Emphasis • Use real equipment, do your own thing • Do your own background reading • Technical writing for physics (satisfies USNA capstone requirement)

  6. FIND AVAILABLE DOCUMENTATION sheets & manuals, Melissinos suggestion sheets SP324 FIND PARTS FIGURE OUT WHAT TO DO SP425 ASSEMBLE TAKE PRELIM DATA and do quick analysis to verify correct assembly & parts working YOU FOUND IT, YOU FIX IT* Good to Go ? TAKE GOOD DATA and analyze MAKE ADJUSTMENTS How can results be improved? FINAL ANALYSIS WRITE REPORT *If it’s broken, inform JeffV
