BCS Energy Gap & London Penetration Depth — 2D Phase Diagram

2D phase-diagram view of BCS superconductivity: watch the energy gap and condensate fraction curves live against temperature, and a 2D depth cross-section of the Meissner field decay and Cooper-pair density.

This is the 2D-native counterpart to the 3D superconducting-slab simulator: the same BCS energy gap Δ(T) and London penetration depth λ(T) physics, rendered as two linked scientific diagrams instead of a populated 3D scene. The top panel is a live phase diagram tracing the gap and condensate-fraction curves against temperature; the bottom panel is a 2D depth cross-section showing the Meissner field's exponential decay and a statistical scatter of paired vs normal electrons. Switch between three real elemental superconductors (Nb, Pb, Sn), sweep temperature through T꜀, and read the instantaneous gap, condensate fraction and penetration depth live.

A 2D phase-diagram view of BCS superconductivity: watch the energy gap Δ(T) and condensate fraction nₛ/n traced live as curves against temperature, alongside a 2D depth cross-section showing the Meissner field's exponential decay and a scatter of Cooper pairs versus normal quasiparticles.
