Content and learning outcomes

Course contents *

  • The basic ideas and concepts of quantum mechanics: Hilbert spaces, bra-ket formalism, operators, matrix representation, observables, the measurement process, uncertainty relations, the position and momentum representation, density matrices, Bell's inequalities.
  • Quantum dynamics: temporal evolution, Schrödinger and Heisenberg picture, the propagator, path integrals.
  • Harmonic oscillator, creation and annihilation operators.
  • Symmetries in quantum mechanics: translation, rotation, parity, spatial and temporal inversion.
  • The theory of angular momentum: ladder operators, spin, addition of angular momentum.
  • Permutation symmetry, identical particles.
  • Approximation methods for time-independent and time-dependent problems, the interaction picture.

Intended learning outcomes *

After completion of the course you should be able to:

  • describe the formal structure of quantum mechanics.
  • apply Dirac's bra-ket notation, and manipulate Hermitian and unitary operators in quantum mechanical derivations.
  • describe in detail the time evolution of quantum systems, the propagator, and the Schrödinger and Heisenberg pictures.
  • know the path integral formulation of quantum mechanics.
  • calculate the expectation value of various physical quantities and how the measurement process works in quantum mechanics.
  • solve the Schrödinger equation for various problems, such as the harmonic oscillator using algebraic methods.
  • use statistical operators (density matrices).
  • know something about quantum mechanics interpretations and Bell's inequalities.
  • describe in detail the consequences of discrete and continuous symmetries and conservation laws.
  • calculate different aspects of the angular momentum and spin, for example, addition of angular momentum.
  • analyze systems consisting of identical fermions or bosons.
  • describe the Aharonov-Bohm effect.
  • apply the main approximation methods for stationary and time-dependent quantum mechanical problems.
