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. ...

A symmetry is usually described by transformations and an associated group. However, a symmetry can also be described by the conservation of charges, encoded by their fusion rule. This leads to a description of symmetry based on fusion category...

We will discuss the geometry behind the horizon of various asymptotically AdS black holes when the boundary CFT is deformed by a scalar operator. The dynamics of classical GR in the region inside the black hole turns out to be rather intricate, with...

We review some recent progress towards  understanding   holographic duality for quantum gravity in asymptotically flat four-dimensional spacetimes.

We consider the universality of existence and saturation of asymptotic bounds in various quantities in 2D CFT. In particular, we focus on previously derived upper and lower bounds on the number of operators in a window of scaling dimensions [???,?+?...
