| 14:00 - 15:00 Weekly Seminar HEPCo Group Warm axion inflation as a way out of TCC School PHYSICS Abstract: Axion warm inflation has been introduced as an alternative to standard (cold) inflation. Coupling between inflaton (axion) field and gauge fields changes the evolution of scalar field even at the background level. It was discussed that the system with this coupling can be thermalized inherently and is protected against tachyonic instability. I will discuss that this scenario is compatible with observation and is in the landscape of quantum gravity conjectures. Date: Tuesday, July 20th 2 p.m. - 3 p.m. (Tehran time) ... |
