LEARNING OUTCOMES
After completing the course the student
- Is familiar with the structure and postulates of quantum mechanics
- Can differentiate between the terms quantum-mechanical state and wavefunction

- Can integrate the quantum evolution and the expectation values of physical quantities for simple systems.
- Can apply creation and annihilation operators to analyze one-dimensional harmonic oscillator.
- Can solve the eigenstates of the one-dimensional harmonic oscillator.
- Can predict measurent probabilities from a given quantum state.
- Can apply perturbation theory to compute eigensolutions in a situation where analytical solutions is challenging.
