| dc.description | It is first shown that the thermal fluctuation effects on the transport and on the thermodynamic observables above the superconducting transition may provide, when they are analyzed simultaneously and consistently, a powerful tool to access the relaxation time, τ<sub>0</sub>, of the Cooper pairs with wave vector k = 0 in high-temperature cuprate superconductors (HTSC). Then, we apply this procedure to optimally doped YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7 − δ</sub> (Y-123) crystals. It is found that in this HTSC τ<sub>0</sub> follows, within 20% accuracy, the BCS temperature behaviour and amplitude given by τ<sub>0</sub> = πℏ/[8k<sub>B</sub>(T − T<sub>c0</sub>)]. |
