Quantum Optics I
Official description
Topics:
PHY2203 explores atomphoton interactions on a semiclassical treatment. How does a quantum system respond to a classical drive field? We begin by discussing why an atom driven by an optical field reduces to a dipole interaction Hamiltonian. The atomphoton problem can then be mapped onto the problem of a spin onehalf electron in a magnetic field, since both are driven twolevel quantum systems. We develop the Bloch equations, Rabi oscillations, and magnetic resonance. Returning to the optical regime, damping is necessary, and thus a treatment using density matrices. Dynamics of the density operator are described by the Optical Bloch Equations, with which one can understand a wide range of current experiments in AMO (atomic, molecular, and optical) physics and solidstate physics. These quantum dynamics are contrasted to classical (Lorentzmodel) dynamics, such as quantum saturation. In the context of a diagonalized atomphoton Hamiltonian, we discuss inversion, dressed states and light shifts. Applications of this foundational material include electromagnetically induced transparency, slow light, dark states, and laser cooling. Time permitting, we will introduce some basic features of the quantum theory of light, including nonclassical states of light, and twophoton interference.
Background:
The material presented will assume mastery of quantum mechanics at the advanced undergraduate level  including timedependent perturbation theory, density matrices, central potential problems, operator treatment of the simple harmonic oscillator, and additional of angular momenta. Advanced undergraduate electricity and magnetism is also important  solutions to the wave equation, polarization, and radiation. We will refer to topics in statistical mechanics that include the BoseEinstein distribution, equipartition, blackbody radiation, and the MaxwellBoltzmann distribution.
