Prerequisites: Fundamentals of quantum physics and structure of matter.
Target skills and knowledge: The aim of the course is to provide students with competences of atomic and molecular physics and of quantum statistics.
Examination methods: Oral exam about topics discussed during lectures.
Assessment criteria: It will be evaluated the acquired degree of knowledge and understanding of the concepts and principles of the course.
Course unit contents: 1) Solution of the Schroedinger equation for a system of two particles in a central potential. Spherica harmonics and radial solution. Relevant expectation values. Virial theorem for a one-electron atom.
2) Time independent perturbation theory (non degenerate and degenerate case). Examples. Time-dependent perturbation theory: perturbation switched on at to and then constant, periodic perturbation.
3) Interaction of one-electron atom with an electromagnetic field. Transition rate, dipole approximation, cross section for stimulate absorption/emission. Spontaneous emission. Selection rules for one-electron atoms. Spin of photons: Beth experiment. Sum rule.
4) Lifetime of an electronic state. Line shape: pressure and Doppler broadening. Examples. Laser, maser. Ammonia maser, solid-state laser. Modern spectroscopies: two-photon sub-Doppler spectroscopy, sub-Doppler saturation spectroscopy, quantum beats.
5) Photoelectric effect: cross section for one-electron atom in 1s state. Comparison with experimental data.
6) Scattering: differential cross section for elastic and inelastic (Rayleigh and Thomson) scattering. Partial waves and corresponding cross section calculation.
7) Electron spin, Stern and Gerlach experiment. Composition of angular momenta. Fine structure of one-electron atoms: spin-orbit, Darwin and relativistic terms. Calculation of some electronic energy levels for on-electron atoms. Lamb shift. Elements of hyperfine structure.
8) Zeeman effect: normal (examples, observed transitions and polarization, Paschen-Bach case), anomalous, case of ultra strong magnetic fields.
9) Stark-Lo Surdo effect for one-electron atoms: linear (n=1, n=2) and quadratic (n=2). Atomic static polarizability. Quenching of the 2s state of hydrogen. Ionization indiced by an electric field.
10) Many-electron atoms. Triplet and singlet states. Pauli exclusion principle (strong and weak conditions). Helium atom (independent electron model, nuclear effective charge). Ground state for a two-electron atom: first order perturbation. Pure discrete excited states, Auger effect. Variational method and application to for the ground state of a two-electron atom.
11) Central potential for a two-electron atom. Hartree theory and results. Slater determinant. Note on the Hartree-Fock method. Results, periodic table of the elements.
12) Correction to the central field: L-S coupling (examples of electronic configuration, degeneracy.). j-j coupling.
13) Molecules: Born-Oppenheimer approximation. Schroedinger solution of H2+ molecule by linear combination of atomic orbitals and of H2. Vibrational and rotational dynamics.
14) Quantum statistics, occupation index: Bose-Einstein and Fermi-Dirac cases with examples.
Planned learning activities and teaching methods: Lectures in Italian.
Additional notes about suggested reading: The topics of the course can be complemented/deepened with the help of the suggested textbooks.
