Bounce Universe as a Viable Alternative to Inflation

Speaker:Prof. Yeuk-Kwan Edna Cheung
Affiliation:Professor of Physics, Nanjing University
Date:March 1, 2018 (Thursday)
Time:4:30 p.m.
Venue:Room 522, 5/F, Chong Yuet Ming Physics Building, HKU


A scale invariant spectrum of primordial matter perturbations has been recently obtained from a bounce universe model constructed from string theory. We will give an overview of the bounce universe scenario. We will then present an explicit construction of the CST bounce cosmos, the scale invariance of the primordial density perturbations (that eventually becomes the matter content of the universe) matched up well with Cosmic Microwaves Background Radiation detected today, and how our model can solve the cosmic singularity problem. A few further developments for investigating matter and anti-matter asymmetry generation in the bounce universe, gravitational waves spectrum computations will be presented briefly.

Coffee and tea will be served 20 minutes prior to the seminar.

Anyone interested is welcome to attend.
