Description
We introduce thermal equilibrium condition in open EFT of inflation, and use this framework to explore the phenomenological aspects of thermal inflation. This talk includes three parts:
1. the dynamical KMS condition for open EFT of inflation and non-perturbative Green functions, including comparison with thermal field theory in de Sitter spacetime
2. The equilibrium constraints on EFT parameters, power counting and scalar power spectrum/non-Gaussianity
3. Discussion on UV models of thermal inflation and top-down open EFT
