Outline

This is a summary of what we covered both in the classroom and from the book.  The exact time line may not be correct since we sometimes reviewed and extended material covered in earlier lectures.

 

LECTURE

  • Week 1 (1,2,3)
    • Review of basic ideas:
      • solutions to classical equations orbits
      • what is a particle
      • what is an interaction
      • Newton’s laws
      • Space-time
      • What are waves
        • Interference
        • Fourier transforms (frequency-time relationship)
      • Vectors, vector mathematics
      • Vectors , Four vectors, Tensors ,Rotations
      • Groups
        • collection of objects such as rotations.
          • Members of a group can be combined (successive rotations)
          • Identity and inverse
          • Combinations can be represented as a single group member (a sum of rotations can be considered as one single rotation)
          • Rotations,
          • translations (space and time),
          • Lorentz and Galilean velocity transformations.
    • Recognized that vectors could be defined by their transformation properties.
          •  

·       Reviewed matrix representations

o      Row and column vectors

o      3x3 matrices

o      4x4 matrices

·       Formulation of relativity.

o      Four vectors

o      Lorentz transformation

o      Field tensor Fμν

  • Week 2 (4,5,6)
    • Quantum mechanics
      • Quantum states form a vector space (Hilbert space).

·       A QS can be written as a linear combination of other QS.

o      Tuning forks can be represented as a string of local pressures (snaps)

o      Snaps can be decomposed using the Fourier transform (tuning forks)

·       Certain sets of states can form  a basis

·       As vectors one can compute an inner product.

o      Orthogonality: No overlap between QS. This implies that the states are chosen to be completely distinct in some way. There is a label that can be used to completely distinguish state 1 and state 2.

o      Overlap: State can share some characteristic. Two states may both have some likelihood of being at some location.

·       Operators may represent observables so their behavior and interpretation tells us how to think about particle properties.

o      Interference

o      Labeling states

o      Two slit, photon polarization

o      What are quanta: Observations or measurements will record many discrete quantities rather than a continuum

o      Amplitudes: To account for the wave nature of QM amplitudes are used.

o      Hilbert space: quantum states as vectors.
