Under the approximation of this name, a cyclic process results in a net geometric phase known as Berry's phase.
In the context of structure formation, primordial perturbations are divided between this type and isocurvature perturbations. Under the approximation of this name, a cyclic process results in a net geometric phase known as Berry's phase. For finite motion, the action variable is an invariant of this type. By the theorem of this name, a discrete, non-degenerate eigenstate will go to the corresponding final eigenstate if the system evolves between initial and final Hamiltonians sufficiently slowly. The atmospheric lapse rate of this name uses the assumption that the air is thermally insulated. In thermodynamics, a reversible process of this type is isentropic. FTP, give this term used to denote processes in which there is no heat flow.
