SPEAKER:
Professor Paul Anderson ,
Colloquium postponed due to weather -- will
be rescheduled
PLACE: George P. Williams, Jr. Lecture Hall, (Olin 101)
TIME: Thursday Feb. 1, 2007 at 4:00 PM
Refreshments will be served at 3:30 PM in the lounge.
All interested persons are cordially invited to attend.
There are two quantum effects which are important in all models of inflation. They are the generation of density perturbations during inflation via quantum fluctuations and the particle production which must occur after inflation to fill the universe back up with matter and radiation. In the first case there is the possibility that unknown very high energy physics could affect the density perturbations and through them leave an imprint on the cosmic background radiation that might be observed. Limits on such processes will be discussed. In the second the details of the particle production process and its effects will be investigated for a particular class of chaotic inflationary models.
