Strange Metal: Quantum-Critical Resistivity Simulator

Tune how far a correlated-electron material sits from a quantum critical point and watch its resistivity switch from ordinary Fermi-liquid T-squared scaling to the T-linear, Planckian-bound 'strange metal' behavior seen in cuprates and heavy-fermion compounds.

Strongly correlated electron materials — cuprate superconductors, heavy-fermion compounds, iron pnictides — often sit near a quantum critical point where a magnetic or charge order vanishes exactly at zero temperature. This simulator visualizes what that proximity does to electrical resistivity: a lattice of conduction electrons scatters more or less often depending on how close the tuning parameter δ is to the critical point, and the live plot tracks the crossover from ordinary T² Fermi-liquid scaling to the T-linear "strange metal" scaling capped by the Planckian scattering bound ħ/τ ≈ k_BT. Tune δ and T to watch the local exponent n slide between 1 (strange metal) and 2 (Fermi liquid).
