Principal mechanism: a dilution refrigerator circulates helium-3 through a helium-3/helium-4 mixture. Mixing at the cold stage absorbs heat. A pulse-tube precooler reduces the temperature of the upper thermal stages. These physical mechanisms are genuine; the animation is not a thermal-fluid simulation.
Textbook physics: E = h f; λ₀ = c/f; n̄ = 1 / (exp(h f / kᴮT) − 1), with exact SI constants h = 6.62607015×10⁻³⁴ J·s, kᴮ = 1.380649×10⁻²³ J/K and c = 299792458 m/s. The photon formula applies to an ideal thermal equilibrium oscillator mode, not an estimate of an actual chip's fidelity.
Independent check: calculate E again from h c / λ₀; compare that value with h f. The readout displays both and their difference.
Illustrative inputs: frequency and mixing-chamber temperature are adjustable teaching values, not measurements. The model's scale, number of cables, temperature-stage geometry, alignments and chip layout are engineering-inspired reconstructions. Small lithographic patterns, flow glows and animated pulses are simplified educational representations. No speculative performance claim is made.
