Course Objectives:

 

After successfully completing this course, students should be able to:

 
 

 Understand the classic experiments leading up to quantum mechanics, including the study of blackbody radiation, the photoelectric effect, the Compton effect, spectroscopic observations, the Davisson-Germer experiment, and the Stern-Gerlach experiment.

 

 Understand the development of the old quantum theory including the deBroglie hypothesis of matter waves and the Bohr theory of the atom.

 

 Understand the Heisenberg uncertainty relations through the eyes of the Heisenberg microscope.

 

 Understand the development and meaning of the Schrodinger equation for the wave function and to relate it to such experiments involving superposition principle such as the Young double-slit experiment.

 

 Solve the Schrodinger equation for one-dimensional problems including the square well and the harmonic oscillator.

 

 Solve the Schrodinger equation for one-dimensional problems including step-potential penetration and tunneling through a barrier, 

 

 Extend the range of applicability of the Schrodinger equation by applying the WKB approximation to both bound state and scattering problems in one dimension.

 

 To understand the Bloch theory for a one-dimensional solid and to do simple band theory calculations.

 

 To learn how to apply the variational principle to broaden the class of potentials that may be studied in quantum mechanics.

 

 To understand the role played by spin and statistics in the application of quantum mechanics to atomic physics.
