EFT Coffee: Qiuyue Liang, "EFT for broken spacetime symmetries"

Friday 26 Sept 2025, 13:15 → 14:30 Europe/Zurich

4/2-037 - TH meeting room (CERN)

Meeting for informal discussion of EFT-related topics. 
List of potential papers to be discussed

13:15 → 13:30 Coffee

13:30 → 14:30 Effective field theory for broken spacetime symmetries

In this talk, I will discuss two bottom-up EFTs with broken spacetime symmetries based on 2210.01139 and 2503.14496. The first half of the talk will be constructing an EFT with broken conformal symmetry in 3+1 d spacetime under the phenomenology of ‘’pseudo conformal universe’’; and the second half will discuss how to construct the fractonic symmetry—one of the generalized symmetries— from broken Lorentz symmetry.

Speaker: Qiuyue Liang (university of Tokyo)
