The Schur index from free fermions
Jun Bourdier, Nadav Drukker, Jan Felix
We study the Schur index of 4-dimensional circular quiver theories. We show that the index can be expressed as a weighted sum over partition functions describing sy…
The exact Schur index of SYM
Jun Bourdier, Nadav Drukker, Jan Felix
The Witten index counts the difference in the number of bosonic and fermionic states of a quantum mechanical system. The Schur index, which can be defined for theories with at leas…
On Classical Solutions of 4d Supersymmetric Higher Spin Theory
Jun Bourdier, Nadav Drukker
We present a simple construction of solutions to the supersymmetric higher spin theory based on solutions to bosonic theories. We illustrate this for the case of the Didenko-Vasili…
Holographic RG flows and nearly-marginal operators
Jun Bourdier, Elias Kiritsis
The holographic renormalization group flows associated with marginally relevant operators are analyzed. The associated perturbative and non-perturbative beta-functions are calculat…
