Special Topics in Atomic Physics
Special Topics in Atomic Physics. Instructor: Prof. P.C. Deshmukh, Department of Physics, IIT Madras. The course will begin with the identification of a complete set of compatible observables for the nonrelativistic Hydrogen atom, identify the complete set of 'good quantum numbers', discuss the associated constants of motion, and associated symmetries. The LaplaceRungeLenz vector and the Fock SO(4) symmetry of the Hydrogen atom will be discussed.
This will be followed by a discussion on coupling of Angular Momenta, ClebschGordan Coefficients, Statement and Proof the WignerEckart Theorem. We shall then discuss the relativistic Hydrogen atom, Dirac equation. FoldyWouthuysen Transformation of Dirac Hamiltonian and Lamb shift. Subsequently, the manyelectron atom will be discussed to acquire an understanding of the HartreeFock SelfConsistent Field Formalism. We shall then examine a Perturbative approach to
relativistic effects; this would provide insight in the relativistic quantum mechanics discussed in an earlier unit based on the Dirac equation.
We shall then proceed to discuss methods to probe the atom. The methods are based on the alternative probes which use quantum collisions of atomic targets with probe particles and probing the atom with an electromagnetic field. We shall discuss the connections of these methods through the timereversal symmetry and obtain the quantum solutions using appropriate boundary conditions. We shall obtain expressions for scattering cross sections, and also for photoionization
crosssection and the angular distribution of the photoelectrons. We shall then examine the quantum mechanics of atoms in external fields and study the Stark effect, and also the family of ZEEMAN effect spectroscopies. A brief introduction to the hyperfine structure and its applications in laser cooling of atoms, BEC, atomic clocks etc. will be pointed out.
