Absence of isentropic expansion in various inflation models
The paper says
“Thus, for many inflation models, believed to yield exclusively isentropic inflation, the parameter space now divides into regimes of isentropic and nonisentropic inflation.”

The paper
Abstract
Dynamics of the inflaton is studied when it interacts with boson and fermion fields and in minimal supersymmetric models. This encompasses multifield inflation models, such as hybrid inflation, and typical reheating models. For much of the parameter space conducive to inflation, the inflaton is found to dissipate adequate radiation to have observational effects on density perturbations and in cases to significantly affect inflaton evolution. Thus, for many inflation models, believed to yield exclusively isentropic inflation, the parameter space now divides into regimes of isentropic and nonisentropic inflation.

Most scenarios considered in the literature so far in the context of quantum field theory [ref] , as well as phenomenological models [ref] consider the case where a nearly-thermal bath of radiation is produced concurrently with accelerated expansion from the adiabatic motion of the inflaton field, which may be analyzed within the framework of linear response theory.
