Superconductivity Simulator — Meissner Effect & Cooper Pairs

This superconductivity simulator splits the canvas into a material visualization and a resistance-vs-temperature graph. The material panel animates paired Cooper pairs (green) and unpaired electrons (red) inside a material sample that turns blue when superconducting below Tc. Magnetic field lines deflect around the sample in Type I (Meissner effect), and an Abrikosov vortex lattice of yellow circles appears in Type II above a threshold field. The graph shows the resistance transition at Tc with a current temperature marker and dashed Tc line.

What you can do in this simulation

• Adjust temperature (1–200 K) to cross the superconducting transition
• Set applied B field (0–1.0 T) to trigger vortex lattice in Type II
• Set critical temperature Tc (5–150 K) to match real materials
• Use presets for Lead (Pb), YBCO, NbTi, and MgB₂
• View energy gap (2Δ) diagram showing band gap in meV
