Contents
From mystery to machinery, then dynamics, structure, and the modern frontier.
Two experiments destroy classical intuition — and force a new theory on us.
- 01The Only MysteryBullets, waves, electrons — the double slit and the birth of probability amplitudes.
- 02Stern–Gerlach and the QubitSequential spin filters, states as vectors, and the Bloch sphere.
- 03The Mathematical MachineryHilbert space, Dirac notation, operators, eigenproblems, tensor products.
- 04The PostulatesStates, observables, the Born rule, collapse, and the density operator.
How quantum states move: two-level systems, wave packets, and the oscillator.
- 05Time and ChangeThe evolution operator, ammonia maser, Rabi oscillations, magnetic resonance.
- 06Wave MechanicsWave packets, dispersion, tunneling, bound states in one dimension.
- 07The Harmonic OscillatorLadder operators, coherent states, and the road to phonons and photons.
- 08Sum over HistoriesPropagators, the Feynman path integral, and the classical limit.
Rotations, atoms, perturbations, fields, and collisions — the structure of matter.
- 09Angular Momentum is RotationSU(2), ladder algebra, spherical harmonics, spin versus orbital.
- 10The Hydrogen AtomCentral potentials, the radial equation, orbitals, and the periodic table.
- 11Combining and ConservingAddition of angular momenta, Clebsch–Gordan, parity, time reversal.
- 12Almost-Solvable WorldsPerturbation theory, variational method, fine structure, the golden rule.
- 13Charges in FieldsLandau levels, gauge invariance, and the Aharonov–Bohm effect.
- 14ScatteringCross sections, the Born approximation, partial waves, resonances.
Identical particles, quantum matter, quantum light, and entanglement.
- 15Identical ParticlesBosons, fermions, exchange, and the language of second quantization.
- 16Quantum MatterFermi gases, Hartree–Fock, Bose–Einstein condensation, BCS pairing.
- 17Quantum LightQuantizing the field, photons, spontaneous emission, dressed atoms.
- 18Entanglement and InformationEPR, Bell's theorem, teleportation, and the quantum computing primer.
