Nonlinear bulk viscosity and inflation
Research output: Contribution to journal › Article › peer-review
We develop a nonlinear generalization of the causal linear thermodynamics of bulk viscosity, incorporating the positivity of the entropy production rate and the effective specific entropy. The theory is applied to viscous fluid inflation ~which is necessarily far from equilibrium!, and we find thermodynamically consistent inflationary solutions, both exponential and power law.
