Abstract
A one-dimensional Ginzburg-Landau model in a random external field is considered. By using the replicated Hamiltonian, it is possible to reduce the problem of calculating the free energy to that of calculating the ground-state energy of a quantum-mechanical problem. The free energy is lowered and the specific heat is raised beyond the respective zero-field values and, as a function of temperature, the specific heat shows a peak.
