Abstract: Type II string theory has BPS brane bound states that carry two charges. I will show that their microcanonical ensemble average corresponds to a spherical black hole mimicker, which possesses a long throat, shares the same asymptotic data...

Princeton University Dark Cosmos Seminar

March 04, 2025 | 4:00pm - 5:30pm

Abstract: Massive neutrinos suppress the growth of cosmic structure on small, non-linear, scales. There is thus much interest in using statistics beyond the power spectrum to tighten constraints on the neutrino mass by extracting additional...

Princeton University High Energy Theory Seminar

February 24, 2025 | 2:30pm - 3:30pm

Abstract: I will present the proof of a conjectured relation between the energy-momentum tensor and the displacement norm of superconformal defects. I will discuss implications for the definition of an invariant tension in Anti-de Sitter gravity...

IAS Physics Group Meeting

February 19, 2025 | 11:00am - 12:15pm

Abstract: Can we regularize chiral global symmetries and their anomalies on a lattice with a finite dimensional Hilbert space? We discuss how the vector and axial U(1) symmetries of a massless Dirac fermion in 1+1d are realized in the conventional...
