| Popis: | We discuss how dissipative effects and the presence of a thermal radiation bath, which are inherent characteristics of the warm inflation dynamics, can evade the recently proposed Swampland conjectures. Different forms of dissipation terms, motivated by both microphysical quantum field theory and phenomenological models, are discussed and their viability to overcome the assumed Swampland constraints is analyzed. Comment: 10 pages, 2 figures. Version matching the published one. Title changed by PRD editorial office. Added a note about the refined Swampland conjectures and also about some recent related work |
