James Chryssanthacopoulos, David Vegh
In the supersymmetric SYK model with fermions, every BPS state is fortuitous: at fixed charge, it exists only over a finite range of . Allowing the charge to…

Quantum mechanical bootstrap without inequalities: SYK bilinear spectrum
Kok Hong Thong, David Vegh
We study a quantum mechanical system whose spectrum coincides with that of bilinear operators of the Sachdev-Ye-Kitaev model. The standard positivity-based quantum mechanical boots…
