title: Dynamic heat capacity in spatially restricted systems with phase transition.
abstract: The frequency-dependent complex heat capacity has been derived for spatially restricted systems with a bulk phase transition. It is demonstrated that internal energy relaxation is determined by the eigenvalues of the Fokker-Planck operator, providing an insight into the symmetry of the reduced free energy. The size driven properties of the energy relaxation rates are discussed and the universal ratio between them has been found.
