Spectroscopy of atoms and molecules

The lecture is intended for students interested in learning methods that can be applied to study properties of atoms and molecules, in particular using laser technology. Courses required to register for the class: Quantum Mechanics I, Introduction to Optics and Condensed Matter Physics. Students are strongly encouraged to have completed courses that covered atom matter interaction and atomic and molecular structure, in particular courses: Atoms, clusters and molecules; Laser Physics.

Program

1. Introduction to spectroscopic methods and their relevance to modern physics.

2. Laser spectroscopy with Doppler width-limited resolution, e.g. absorption spectroscopy, ionization spectroscopy, cavity ring-down spectroscopy, optical pumping

3. Spectroscopy with frequency combs

4. Raman spectroscopy

5. Doppler-free spectroscopy and its application to laser frequency stabilization:

a. laser spectroscopy in atomic and molecular beams

b. supersonic beams

c. saturation spectroscopy

d. polarization spectroscopy

e. two- and multiphoton spectroscopy

6. Time-resolved spectroscopy

7. Mass spectroscopy

8. Terahertz spectroscopy

9. Spectroscopy in the ultracold regime:

a. photoassociation spectroscopy

b. particle loss spectroscopy

c. binding energy measurement

d. spectroscopy of atoms in optical lattices

e. quantum logic spectroscopy in ion clocks

f. fluorescence measurement

10. Application of spectroscopic methods in chemistry, medicine and technology

1. W. Demtröder, Spektroskopia laserowa.

2. A. Corney, Atomic and laser spectroscopy.

3. S. Svanberg, Atomic and Molecular Spectroscopy.

4. J.M. Hollas, Modern Spectroscopy.

5. Cheng Chin, Rudolf Grimm, Paul Julienne, and Eite Tiesinga, Feshbach resonances in ultracold gases, Rev. Mod. Phys. 82, 1225 (2010)

6. Kevin M. Jones, Eite Tiesinga, Paul D. Lett, and Paul S. Julienne, Ultracold photoassociation spectroscopy: Long-range molecules and atomic scattering, Rev. Mod. Phys. 78, 483 (2006)

The students will be familiar with modern spectroscopic techniques utilizing laser, microwave and rf radiation and will be able to apply these techniques in their work. The student will know the basic principles of the scientific apparatuses used in spectroscopic measurements and will be able to choose a proper technique to measure the properties of atoms and molecules and interpret the results of the measurements.
