Short · Sheffield
Quantum Light University of Sheffield
A two-minute animation from a quantum-optics research group showing two indistinguishable single photons that reach a beam splitter at the same moment always leaving together. Watch it right after the paragraph on the 1987 Rochester experiment to see the Hong–Ou–Mandel dip happen.
Lecture · MIT
MIT Video Productions · Wolfgang Ketterle
Ketterle, whose MIT group made the large sodium condensates in this section and who shared the 2001 Nobel Prize for them, tells the story of Bose–Einstein condensates in an hour-long Nobel Laureate Lecture at MIT. A far fuller account than the briefing's ten-minute Serious Science interview; watch it once the thermal-wavelength criterion makes sense.
Demo · Harvard
Harvard Natural Sciences Lecture Demonstrations
Harvard's lecture-demonstration team shows a permanent magnet beginning to hover above a ceramic sample as it cools into its superconducting state. Watch for the lift itself: a merely perfect conductor would keep the field already inside it, so the magnet rising is the Meissner effect's expulsion at work.
Lecture · Stanford
Stanford Institute for Theoretical Physics · Steven Kivelson
A Stanford theorist introduces superconductivity as quantum mechanics made visible at the scale of everyday objects, in the first of a two-part series. Long and unhurried: the place to go when the Cooper-pair sketch in this section leaves you wanting the full picture.
Lecture · Tel Aviv
TAUVOD · Douglas Osheroff
Douglas Osheroff, one of the three Cornell physicists who shared the 1996 Nobel Prize, tells the story behind finding superfluidity in helium-3 in a lecture at Tel Aviv University. A first-hand account of the fermion superfluid that appears only after its atoms pair, at thousandths of a kelvin.
Lecture · MIT
MIT OpenCourseWare · Allan Adams · 2013
The lecture from MIT 8.04 Quantum Physics I (Allan Adams, 2013) that goes with Chapter 19. The whole course is in the Lecture Hall.
Course · MIT
MIT OpenCourseWare · Allan Adams · 2013
Allan Adams' celebrated course starts from superposition and the experimental facts, builds the wavefunction, operators and the Schrödinger equation, then tours scattering, hydrogen, identical particles and band structure before closing on entanglement and Bell's theorem. Calculus and a little linear algebra are enough to keep up.
Course · MIT
MIT OpenCourseWare · Barton Zwiebach · 2018
For the ambitious: perturbation theory and the fine structure of hydrogen, the semiclassical WKB approximation behind tunnelling rates, the adiabatic theorem, scattering, and identical particles, in 100 compact segments.
Explainer · Fermilab
Fermilab
Fermilab's Dr. Don Lincoln introduces the two great families of particles and how spin decides which family a particle joins. Watch for why fermions build the structure of matter while bosons are free to crowd together: that contrast is the spine of today's session.
Explainer · YouTube
PBS Space Time
Goes beneath the slogans into the counting itself: how treating particles as truly identical changes the number of distinct arrangements, and how that produces the Fermi–Dirac and Bose–Einstein distributions you will meet in Part 3. Best watched after the lesson.
