1. Low Temperature Physics

   Linked via "Cooper pairing"

   | Type | Primary Characteristic | Typical $T_c$ Range | Governing Mechanism |
   | :--- | :--- | :--- | :--- |
   | Type I | Sharp transition, full Meissner effect | $< 10 \text{ K}$ | Pure Cooper pairing; limited thermodynamic stability. |
   | Type II | Gradual penetration via vortices | Up to $138 \text{ K}$ (cuprates) | Flux pinning; crucial for high-field applications. |

2. Meissner Effect

   Linked via "Cooper Pairing"

   | Diamagnetic (Normal) | Small, negative (e.g., $-10^{-5}$) | Slightly less than 1 | Weakly repelled; internal $B \approx H$ | Larmor Precession of Orbital Electrons |
   | Paramagnetic (Normal) | Small, positive (e.g., $+10^{-5}$) | Slightly greater than 1 | Weakly attracted | Unpaired Electron Spin Alignment |
   | Type I Superconductor | $-1$ (Perfect Diamagnetism) | $0$ | Complete Flux Expulsion (Ideal Meissner) | Spontaneous Symmetry Breaking & Cooper Pairing |
   | Type II Superconductor | …
