 I will discuss real-time path integrals in gravitational theories. As applications we will describe the general structure of replica wormhole saddles and the effective dynamics of open quantum systems with long-term memory.

In recent work, it was argued that quantum computations with inputs and outputs distributed in spacetime, or quantum tasks, impose constraints on entanglement in holographic theories. The resulting constraint was named the connected wedge theorem...

I will discuss progress towards understanding the relationship between the gravitational path integral and the partition function via the gravitational free energy (more generally the generating functional). A proper computation of the free energy...

I'll talk about two related projects, with two different groups, both aiming to see three-dimensional manifolds "from the inside". That is, we generate images assuming that light travels along geodesics in the geometry of the manifold. The first...

Emily Wilson read from her upcoming translation of Homer's The Illiad.

Let GG be a reductive group over a number field FF and HH a subgroup. Automorphic periods study the integrals of cuspidal automorphic forms on GG over H(F)∖H(AF)H(F)∖H(AF). They are often related to special values of certain L functions. One of the...

NASA's Kepler mission conducted a large survey of planetary systems.  Recently, we have advanced from measuring occurrence rates as a function of planet size and period to characterizing the intrinsic distribution of planetary system architectures. ...

Before the "geometric Satake equivalence" there was a decategorified version of it which however contained most of its essential features. In my talk I will talk about some of the ideas which have led to this theory. In particular I will explain the...

Several well-known open questions (such as: are all groups sofic/hyperlinear?) have a common form: can all groups be approximated by asymptotic homomorphisms into the symmetric groups Sym(n)Sym(n) (in the sofic case) or the finite dimensional...
