Studying atoms, molecules, and their interactions, as well as how they are used in disciplines like quantum mechanics, spectroscopy, and material science, is the main focus of a Ph.D. program in atomic and molecular physics. Depending on the status of the study, the program usually takes 3-5 years to finish. Students study subjects like atomic structure, laser-matter interactions, molecular dynamics, and quantum optics through sophisticated experimental and theoretical research. A master's degree in physics or a similar discipline is often required for admission. Graduates of this program are equipped for jobs in physics and related fields in academia, industry, and research.
