Synopsis and goals of the course
The course will be devoted to solving a variety of physics problems. Wherever possible and appropriate, we will try to use, in place of a formal mathematical solution, approximate methods, such as dimensioanal analysis, perturbation theory, etc. Some of the topics we might cover in the problems include:
1. Estimates, estimates… Estimation techniques, units, orders of magnitude, statistics, common sense problems.
2. Simple atoms. Hydrogen, hydrogenic ions, Geonium, hydrogen-like atoms (muonium etc.), fine and hyperfine structure, Zeeman and Stark Effects, atomic polarization.
3. Multi-electron atoms. Helium, the periodic table, lanthanides and actinides, Hund's rules, configurations and terms, Thomas-Fermi model, isotope shifts and hyperfine structure.
4. Simple molecules. Electronic, vibrational and rotational levels, quantum statistics and molecular levels, hyperfine structure and isotope shifts, molecular dipole moments.
5. Atoms, molecules and light. Emission, absorption, scattering, resonance fluorescence, collective effects, Hanle and Faraday effects.
6. Experimental methods. Optical pumping, magnetic resonance, Ramsey's method, atomic beams, high-resolution laser spectroscopy, quantum beats, laser cooling and trapping, light-induced drift, Bose-Einstein Condensation, nonlinear magneto- and electro-optics, fundamental symmetry tests.
7. Lasers, optics, quanta. Optical resonators and interferometers, physics of various types of lasers, QED, cavity QED, nonlinear optics.
8. Atomic Nuclei. Atomic physics methods in nuclear physics, cold and ultra-cold neutrons, laser-driven fusion.
Our approach to posing and solving the problems is based on the desire that the problem contains at least one "memorable" physics idea, and would admit an elegant solution, not requiring elaborate mathematics. We hear from students to whom we offered many of these problems in other classes, that they are frequently amazed by unexpected physical insights that can be gained from solving these seemingly straightforward problems.

Assignment 1 (due March 21)
Consider the interaction of light of wavelength l with small spherical metal particles of radius a<< l. Estimate the power absorbed by the particle per unit time. To solve this problem, devise a simple model that captures the essential physical mechanism leading to heating. Discuss the dependence of the absorbed power on the particle size and on the light frequency. Make numerical estimates for the case of silver particles with a=0.3 mm, l=1.06 mm (Nd-YAG laser), and a light pulse with total power 1 J, beam cross-section 1 cm2, and pulse duration of 10 ns. How hot will the particle be at the end of the pulse? Will it be intact?
Assignment 2 (due April 17)
In this problem, we analyze losses in power transmission lines. Although, at first glance, this subject appears quite unrelated to Atomic, Molecular, and Optical (AMO) Physics, as we have seen again and again throughout the semester, all physics is really the same. I promise that this problem will give us valuable AMO insights.
a) Describe a high-power transmission line. Estimate (or find in the literature, or on the web) voltage, current, and the diameter of the wires. Why does the line operate at 60 Hz AC? What determines the distance between wires?
b) "Serious" high-power lines usually have 6 wires. Explain why this is so, and comment on the relative location of the wires.
c) What are the main power-loss mechanisms? Estimate the losses per unit length (in W/m) for a 3-wire and a 6-wire line.
