Course outline (suggestions welcome):

  •  Stern Gerlach experiment, Hilbert space and probability postulate (kets, bras and operators), matrix representations
  •  measurements (eigenvalues and eigenvectors), Uncertainty relations
  •  Classical versus quantum probability (density matrices and entropy)
  •  Applications of quantum indeterminacy (quantum random numbers and cryptography)
  •  Composite systems, entanglement (entropy) and the EPR paradox (Bell's inequality)
  •  Unitary time dynamics of discrete systems - Schrodinger and Heisenberg representations - Bloch sphere dynamics
  •  Continuous variable Hilbert spaces (position and momenta)
  •  Time-dynamics of continuous systems - Heisenberg's equation and Schrodinger's wave-equation (classical limit)
  •  Review elementary solutions of Schrodinger's wave equation (harmonic oscillator, square well, linear potential)
  •  WKB semiclassical approximation,
  •   Propagators and feynman path integrals, gauge potential, Aharonov-Bohm effect, diamagnetism in superconductors, monopoles
  •   Rotations as generators of angular momenta, SO(3) versus SU(2), angular momentum algebra, rotation matrices, spherical harmonics, schwinger bosons
  •  Schrodinger equation for central potentials (3D harmonic oscillator, SO(4) solution to hydrogen atom)
  •  Tensor operators and the Wigner-Eckart theorem
  •  Symmetry and conservation laws for continuous and discrete symmetry - translation and parity violation
  •  Time reversal symmetry and Kramer's theorem
