Residue sums for superconformal indices
Sam van Leuven, Kayleigh Mathieson, Pratik Roy
We study superconformal indices of four-dimensional gauge theories with supersymmetry. The usual representation of a gauge theory index involves multipl…

Two-local modifications of SYK model with quantum chaos
Masanori Hanada, Sam van Leuven, Onur Oktay +1
The Sachdev--Ye--Kitaev (SYK) model may provide us with a good starting point for the experimental study of quantum chaos and holography in the laboratory. Still, the four-local in…

To gauge or to double gauge? Matrix models, global symmetry, and black hole cohomologies
Adwait Gaikwad, Tanay Kibe, Sam van Leuven +1
We study the structure of the Hilbert space of gauged matrix models with a global symmetry. In the first part of the paper, we focus on bosonic matrix models with gauge grou…
