Princeton University Dark Cosmos Seminar

November 05, 2024 | 4:00pm - 5:00pm

Abstract: Arising in hidden sector models of dark matter, millicharged particles could be produced copiously at facilities such as the LHC. However, due to their very small energy depositions, large detectors like CMS or ATLAS are blind to such...

IAS Amplitudes Group Meeting

November 05, 2024 | 2:30pm - 4:00pm

Abstract: Is there a geometric object underlying the cosmological wavefunction for Tr $\phi^3$ theory, just as associahedra underlie scattering amplitudes? In this talk, I will describe a new class of polytopes that answer this question. I will...

IAS High Energy Theory Seminar

November 01, 2024 | 11:00am - 12:15pm

Abstract: I will discuss dilaton gravity with a sine potential, where periodic shifts of the dilaton (that leave the potential invariant) are treated as a redundancy. Most things I will say hold true for generic periodic potentials, but the sine...

IAS Quantum Aspects of Black Holes Group Meeting

October 31, 2024 | 11:00am - 12:00pm

Abstract: I will discuss a geometric approach to the factorization puzzle that involves coadjoint orbits and Berry phases. The mathematical formalism introduced is applied both to quantum mechanics examples and to AdS/CFT.  It is shown how the...

IAS Amplitudes Group Meeting

October 29, 2024 | 2:30pm - 4:00pm

Abstract: Consider the interaction of one-dimensional surface gravity waves on top of an ideal fluid of infinite depth. Notably, for certain orientations of the wave vectors, the interaction matrix element vanishes, while for other orientations, the...
