pp Waves: Quasinormal Modes & Hidden Symmetries of Black Holes

CMSA, 20 Garden St, G10 20 Garden Street, Cambridge

The spectrum of quasinormal modes of 4D flat space black holes is not analytically tractable, but there are two asymptotic limits where the QNM spectrum is under control: weak damping […]

Characteristic classes of singular varieties

Science Center Hall A 1 Oxford Street, Cambridge

In the case of manifolds, Hirzebruch showed how to unify the theories of characteristic classes of Chern, Todd and Thom-Hirzebruch. These three theories have been generalized to the case of […]

Universal Circuit Set with S3 Quantum Double

Jefferson 356

One potential route toward fault-tolerant universal quantum computation is to use the non-Abelian topological codes. In this work, we investigate how to perform computation with a specific non-Abelian topological order---the […]
