Skip About this course

This is the second of five modules to introduce concepts and current frontiers of atomic physics and to prepare you for cutting-edge research:

8.421.1x: Resonance

8.421.2x: Atomic structure and atoms in external field

8.421.3x: Atom-Light Interactions 1 -- Matrix elements and quantized field

8.421.4x: Atom-Light interactions 2 -- Line broadening and two-photon transitions

8.421.5x: Coherence

The second module, 8.421.2x, describes atomic structure, including electronic levels, fine structure, hyperfine structure and Lamb shift. You will then learn about how electric and magnetic fields shift atomic levels. The discussion of time-dependent electric fields prepares you for the interactions of atoms with light and for the dressed atom picture.

At MIT, the content of the five modules makes the first of a two-semester sequence (8.421 and 8.422) for graduate students interested in Atomic, Molecular, and Optical Physics. This sequence is required for Ph.D. students doing research in this field.

In these modules you will learn about the interaction of radiation with atoms: resonance; absorption, stimulated and spontaneous emission; methods of resonance, dressed atom formalism, masers and lasers, cavity quantum electrodynamics; structure of simple atoms, behavior in very strong fields; fundamental tests: time reversal, parity violations, Bell's inequalities; and experimental methods.

Completing the two-course sequence allows you to pursue advanced study and research in cold atoms, as well as specialized topics in condensed matter physics.

FAQ

Who can register for this course?

Unfortunately, learners from Iran, Cuba, Sudan and the Crimea region of Ukraine will not be able to register for this course at the present time. While edX has received a license from the U.S. Office of Foreign Assets Control (OFAC) to offer courses to learners from Iran and Sudan our license does not cover this course.

Separately, EdX has applied for a license to offer courses to learners in the Crimea region of Ukraine, but we are awaiting a determination from OFAC on that application. We are deeply sorry the U.S. government has determined that we have to block these learners, and we are working diligently to rectify this situation as soon as possible.
