Inflation is hot!
This seminar examines the class of inflationary models in which the density fluctuations arise from an excited quantum state during the inflationary era. We will see how to describe thermal fluctuations during inflation and why these lead naturally to distinctive non-gaussian features in the CMB.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
