Seminar:- Understanding the Late-Time Cosmic Acceleration from Dynamical Dark Energy and f(T) Gravity
In this talk the speaker will briefly introduce the present understanding about the cosmic acceleration at present from the perspective of phenomenological study. He will review the latest observational status of the late-time cosmic acceleration and then depict how to do the model building of dynamical dark energy. Afterwards, the speaker will also give an introduction to a type of torsional based modified gravity, which can also realize the cosmic acceleration at present. This so-called f(T) gravity and beyond theories can be depicted in a language of effective field theory and thus we can examine certain operators that are most connected with various cosmological observations.
