Measurement of Transport Lifetime in a Cuprate Superconductor

J. Corson, J. Orenstein, Seongshik Oh +2

We report measurements of the phase of the conductivity, ${\varphi }_{\sigma }\equiv arg(\sigma )$, in the normal state of a $B{i}_{2}S{r}_{2}CaC{u}_2{O}_{8+\delta }$ (BSCCO) thin film from 0.2-1.0 THz. From ${\varphi }_{\sigma }$ w…
