A theoretical study of short-wavelength fluctuation effects on the specific heat above is reported for superconducting thick films with the arbitrary conduction dimensionality between two and three dimensions (2D and 3D). In the present calculations, momentum cutoff effects in the fluctuation spectrum are taken into consideration in the context of the Aslamazov-Larkin theory. Our result covers the...
Effects of the short wavelength fluctuations on the specific heat ΔC in a superconductor are studied within the scheme of the Aslamazov-Larkin (AL) theory. By imposing the momentum cutoff in the fluctuation spectrum, formulae for ΔC are derived in a layered system as well as in n-dimensional (nD) systems (n=1, 2 and 3). Formulae under a total-energy cutoff condition are also presented. It is found...
