Quantum light and atom-photon interactions
Quantize optical modes and analyze photon statistics, cavity coupling, coherent driving, and nonclassical light with operational detector models.
- 01
Quantize one optical mode with explicit normalization
Connect a normalized transverse field mode to oscillator operators, photon energy, and vacuum quadrature noise.
32 min - 02
Separate coherent amplitude from quadrature squeezing
Compare Poissonian coherent-state counts with anisotropic quantum noise and track vacuum admixture under loss.
32 min - 03
Connect field moments to detector counts
Use normal ordering, finite efficiency, and factorial moments to distinguish a source state from its recorded photon-count distribution.
32 min - 04
Distinguish count correlations from two-photon interference
Interpret g², thermal bunching, single-photon exclusion of coincidences, and Hong–Ou–Mandel interference with explicit measurement assumptions.
32 min - 05
Resolve the coupled atom–cavity doublet
Derive excitation blocks, detuned transfer, and the square-root photon dependence of the Jaynes–Cummings model.
32 min - 06
Solve a driven atom with relaxation
Track population, coherence, and saturation with explicit decay-rate and Rabi-frequency conventions.
32 min - 07
Derive decay into a continuum of vacuum modes
Connect dipole coupling and mode density to spontaneous emission while delimiting exponential and Markov approximations.
32 min - 08
Compare coherent exchange with cavity and atomic loss
Distinguish cooperativity, resolvable normal modes, and coherent swaps under one consistent linewidth convention.
32 min - 09
Construct a dark state and test its limits
Derive coherent cancellation in a Lambda atom and connect ground-state dephasing to residual probe absorption.
32 min - 10
Relate intracavity dynamics to the measured output
Declare port phases and linewidths, derive reflection, and preserve vacuum noise while connecting cavity population to external photon flux.
