Hi all,
This friday's seminar (23rd Oct) will be given by Jean-Luc Lehners (Princeton), in Huxley room 503:
Observing the Multifield Cyclic Universes
Abstract:
I will discuss the qualitative differences between the single-field and multifield cyclic universes, in particular the resulting global "phoenix" structure and its relation to dark energy. The multifield cyclic universe leads to distinct observational predictions regarding non-gaussian signatures in the CMB, and I will present a simplified derivation of these predictions.
As with last week we will start at 1pm, and then go to lunch with the speaker. All are welcome.
Jude and Johannes
