Advanced Quantum Mechanics (B-KUL-G0S83A)
Aims
Students acquire a more deeper knowledge on the nature and the power of quantum mechanics. In particular they know how to apply perturbation theory, to employ scattering theory and to apply symmetry arguments. Students also get in touch with more modern aspects of quantum mechanics like in questions about entanglement, non-localities and the measurement problem.
Previous knowledge
Students have followed courses in General Physics, and they also have successfully finished a basic course in quantum mechanics.

Activities
6 ects. Advanced Quantum Mechanics (B-KUL-G0S83a)
Content
1. Reminders: quantumformalism for closed systems, two-slit experiment. Schroedinger equation with spin (Pauli and Dirac equations) - Stern-Gerlach experiment. Quantumstatistics.
2. Complements:
- Time-dependent Hamiltonian, quantum protocol and control;
- Time-dependent perturbation theory (Dyson method);
- Scattering theory (Landauer-Buttiker formula);
- Symmetry considerations (the hydrogen atom revisited);
- Approximations (semi-classical analysis, WKBJ-method, Born-Oppenheimer approximation).
3. Modern developments:
- Open systems, dissipative evolutions, decoherence, Caldeira-Leggett model. Weak coupling (Fermi-Golden rule), Lindblad equation;
- Quantum nature: superposition, entanglement, tunneling, nonlocality;
- Quantum optics. Jaynes-Cummings model, Rabi oscillations, coherent states, squeezing, manipulations of individual atoms;
- Quantum system theory. Positive-operator valued measure, quantum computing and algorithms, compression and capacity.
Depending on available time and taking into account the possible overlap with other courses:
- Introduction to path-integrals (example: Ahoronov-Bohm effect);
- From Einstein-Podolsky-Rosen experiments to Bell inequalities and the Kochen-Specker No-Go Theorems;
- Schroedinger’s cat and possible solutions of the measurement problem.
