IAS High Energy Theory Seminar

The question I will address is: How does the holographic principle apply to de Sitter space? 

This is a continuation of a series of talks I have given in recent years reporting on work with Jan Manschot, et. al.
There will be some repetition, and some updates and new results.   (See below for some relevant links.)
Manschot and I have...

The future interior of black holes in AdS/CFT can be described in terms of a quantum circuit. We investigate boundary quantities detecting properties of this quantum circuit. We discuss relations between operator size, quantum complexity, and the...

I will discuss ongoing work about a string theoretic perspective on the 2d Bethe/Gauge correspondence of Nekrasov-Shatashvili. In this work, we focus on gl(M|N) spin chains. We show that the two sides of the correspondence, the integrable spin chain...

We present spherically symmetric solutions to Einstein’s equations, which are equivalent to canonical Schwarzschild and Reissner-Nordstrom black holes on the exterior, but with singular (Planck-density) shells at their respective event and inner...

With gate error rates in multiple technologies now below the threshold required for fault-tolerant quantum computation, the major remaining obstacle to useful quantum computation is scaling, a challenge greatly amplified by the huge overhead imposed...

 I will revisit the quantum field theory of the Coulomb gas formalism, clarifying several important points along the way. The first key ingredient involves a peculiarity of the timelike linear dilaton: although the background charge Q breaks the...

We will discuss a geometric re-interpretation of N=1 SQCD with special unitary gauge groups. We will argue that the 4d SU(M) SQCD in the middle of the conformal window can be engineered by compactifying certain 6d SCFTs on three punctured spheres. ...
