Condensed Matter Calculator
Analyze band structure, phonon dispersion, and BCS superconductivity with one calculator. Switch unit systems, inspect calculated values, and visualize curves with interactive charts.
Use Cases
- - Tight-binding and bandwidth quick checks
- - Lattice dynamics and phonon frequency estimates
- - BCS critical temperature and gap approximations
- - Student and researcher sanity checks before simulation
Formulas Used
- E(k) = e0 + 2t cos(ka), bandwidth = 4|t|
- omega(k) = 2 * sqrt(k/M) * |sin(ka/2)|
- T_c = 1.14 Theta_D exp(-1 / (N(E_F)V))
- Delta(0) = 1.76 k_B T_c
