Perturbative Dissipation in Minimal Warm Inflation
Daniel J. H. Chung, Nidhi Sudhir, Lian-Tao Wang
We present an analysis of the perturbative modes of dissipation in the minimal warm inflation model where an axion-inflaton is coupled to a gluon thermal bath through the axion-gau…

A topological contribution to Bogoliubov coefficient for cosmological particle production
Daniel J. H. Chung, Nidhi Sudhir
Particle production in cosmology is often efficiently computed in terms of Bogoliubov transforms. Restricting to a particular class of dispersion relationships, we identify a map b…
