چکیده انگلیسی
Effects of short-wavelength cutoffs on the c-axis (out-of-plane) fluctuation conductivity Ïcâ² in a layered superconductor are studied for Aslamazov-Larkin (AL), Maki-Thompson (MT) and density of states (DOS) terms. A theoretical equation for Ïcâ² in each term is derived under two types of the cutoff conditions: a momentum cutoff (MC) and a total-energy cutoff (EC) in the fluctuation spectrum. The MC effect provides appreciable contributions to Ïcâ² of the MT and DOS terms as in the case of the AL term. On the other hand, the EC effect plays no explicit role in Ïcâ² as far as anomalous and regular MT terms are concerned. Difference between MC and EC effects is numerically presented and our results are compared to experiments on Ïcâ².
