Interfacial Entropy Profile in the One-loop Approximation

The near-critical interfacial entropy profile is calculated in the one-loop approximation of renormalized field theory. shape broadened by fluctuations and goes beyond mean-field coupling between order parameter. excess heat capacity are using profile. interface creates corrections to χ/L, where $\xi$ correlation length, L a characteristic length system. These results discussed relation finite-size scaling, surface critical phenomena, experiments simulations.
