Abstract
Free-energy barriers separating metastable incommensurate states are studied theoretically for a simple model of modulated systems. Analogies with superfluid 4He and superconducting wires are exploited. Two types of free-energy barriers associated with the creation of a vortex ring and the unwinding process are identified and are discussed in relation to the decay processes of metastable states.Keywords
