Currently Teaching
PHYS-790
Graduate Research & Thesis
1 - 4 Credits
Graduate-level research by the candidate on an appropriate topic as arranged between the candidate and the research advisor.
PHYS-415
Advanced Quantum Mechanics
3 Credits
This course is a continued study of the concepts and mathematical structure of quantum mechanics presented in Quantum Mechanics (PHYS-414), with an emphasis on applications to real physical systems. Topics covered include the quantum theory of spin, effect of magnetic fields on spin-1/2 particles, many-particle systems, variational principle, time-independent and time-dependent perturbation theory, absorption and emission of radiation by atoms, quantum theory of scattering, and interpretations and paradoxes of quantum mechanics.
PHYS-791
Continuation of Thesis
0 Credits
Graduate-level research by the candidate on an appropriate topic as arranged between the candidate and the research advisor.
PHYS-495
Advanced Physics Research
1 - 3 Credits
This course is a faculty-directed student project or research involving laboratory work, computer modeling, or theoretical calculations that could be considered of an original nature. The level of study is appropriate for students in their final two years of study.
PHYS-414
Quantum Mechanics
3 Credits
This course is a study of the concepts and mathematical structure of non-relativistic quantum mechanics. Topics for the course include wave functions and the Schrodinger equation, solutions to the one-dimensional and three-dimensional time-independent Schrodinger equation, stationary states and their superposition to produce time-dependent states, quantum-mechanical operators, commutators, and uncertainty principles, solutions to general central potential problems and the hydrogen atom, and the quantum theory of angular momentum.
