IAS-PHYS Fundamental Physics Seminar Series - Extending EFT of Inflation/Dark Energy to Arbitrary Background
3:00pm - 4:00pm
IAS 1038, 1/F, Lo Ka Chung Building, Lee Shau Kee Campus, HKUST
Abstract
The speaker extends EFT of inflation/dark energy to arbitrary backgrounds with timelike scalar profiles. In this framework, a set of consistency relations among EFT coefficients ensures the spatial diffeo invariance. He will then apply it to black hole perturbation in the presence of dark energy.
