An important aspect of
the design of this note is to maintain a concise basic treatment of the physics,
with derivations and examples available behind hyperlinks. Topics covered
includes: The Problems with Classical Physics, Diffraction, Wave Packet,
Operators, The Schrodinger Equation, Eigenfunctions, Eigenvalues and Vector
Spaces, 3D Problems Separable in Cartesian Coordinates, Hydrogen, 3D Symmetric
HO in Spherical Coordinates, Electrons in an Electromagnetic Field, Time
Independent Perturbation Theory, Fine Structure in Hydrogen, Atomic Physics,
Scattering, Classical Scalar Fields, Quantum Theory of Radiation, Dirac
Equation.
This note covers the
following topics: Classical Physics, Waves, Probability Density, The Ultraviolet
Catastrophe, Bragg X-ray Diffraction, Wave-Particle Duality, Particles and
Fields, Heisenberg’s Uncertainty Principle, Wavefunctions - Schrodinger’s
Equation, Quantum Tunnelling, Quantum States and Superposition, Two State
Systems, Wavefunction Collapse, Interpretations of Quantum Physics,
Probabilistic Determinism.
Quantum physics is a
catch-all term for the ideas, devices and technologies made possible by the
development of quantum mechanics in the early part of the 20th century. This
note concentrates on the ideas behind quantum mechanics itself, but the broader
field of quantum physics encompasses everything from the science of electronic
devices and lasers to the philosophical mysteries of quantum measurement
theory.
