Solutions are obtained for expansion e-folds and scalar density perturbations. Nonequilibrium dynamics is restricted to a regime that is displaced only slightly from thermal equilibrium and in which all macroscopic motion is adiabatic. In such a regime, nonequilibrium dynamics is well defined, provided macroscopic motions that displace the thermal equilibrium state occur sufficiently slow. The solution has adjustable parameters that permit observational consistency with respect to expansion e-folds and density perturbations in the full adiabatic regime, thus insuring a valid solution regime. For particle physics, the model is nonstandard since it requires a large number of fields, $> 10^4$. A particle physics/string interpretation of the model and solutions is discussed, which can accommodate the large field number requirement.", "revisions": [ { "version": "v4", "updated": "2000-06-27T17:00:19.000Z" } ], "analyses": { "keywords": [ "quantum field theory", "warm inflation", "existence proof", "inflationary dynamics", "state occur sufficiently slow" ], "tags": [ "journal article" ], "publication": { "publisher": "Elsevier", "journal": "Nucl.
