Weak versus Strong Coupling Theory for Bi2Sr2CaCu2O8 |

| Abstract: |
The latest optical determination of the superconducting-gap function for Bi2Sr2CaCu2O8 is consistent with weak-coupling theory. In contrast, a large discontinuity in heat-capacity data suggests strong-coupling superconductivity, and appears to exceed the theoretical strong-coupling limit. A possible resolution to the apparent incompatibility of the two measurements is presented. The apparent disagreement with the results of strong-coupling theory is also resolved. |
