A survey of major topics in modern atomic physics. Topics in atomic structure include general features of atomic spectra, fine structure, hyperfine structure, the Lamb shift, hydrogen, helium, alkali atoms, complex atoms, excited states, and synthetic atoms. Topics in atom-field interactions and atom atom interactions include the DC Stark effect, the Zeeman effect, transitions, two-level systems, stimulated and spontaneous emission, selection rules, lifetimes, line shapes, broadening mechanisms, the AC Stark effect, multiphoton processes, scattering channels, and Feshbach resonances. Also covers modern techniques including spectroscopy, laser cooling, atom traps, quantum gases, cold molecules, trapped ions, and atomic clocks.

Prerequisites: Physics 215A and Phys 210A; or the consent of the instructor.

PHYS3 . 11 Months Ago

She did everything but teach us. I took this class with her F23 and I kid you not she flew out of the country every other day. Gave out the worst exams ever. Super low averages to the point she had to do an insane curve to ensure that most of the class didn't fail.

She may well be a good person and a good researcher, but she should absolutely not be teaching an undergraduate intro course of this nature. Constantly absent from lecture, when she was present her lecture style was confusing and useless compared to reading the textbook(although I still attended). Not worth skipping a qtr but avoid if possible.

This class was.... hard. Everyone stopped going to lecture because she was never there. The tests were crazy hard and felt super out of the class's depth, and she said she would curve and did not. UCSB should just let people stay researchers, some of these profs are geniuses, but are just... incapable of teaching.

Arguably, it was the hardest class I've taken at the school. She's a good person, but I don't think her teaching style helps students learn the material. The second midterm and final were very tough even though I did study quite a bit for each one. Just say a prayer if you're in one of her classes.

Jayich frequently misses class for travel. Her lectures consist of long derivations are are exceptionally hard to follow. She gives limited test resources and makes the midterms and final very difficult. Obviously an intelligent woman but she cares much more about her research than teaching undergrads. Avoid taking any lower div courses with her.

Tbh I never went to lecture, but got an A-. There is no exam review, just hw. If you're not really into physics it's probably very hard, but compared to ME14 (statics) this class is pretty easy. She responds to emails fast, and has good communication about exams. Exams were well made.
