The Levy SYK model is solved exactly at large N, with mu tuning the system from free theory at mu=0 to the standard maximally chaotic SYK at mu=2.
Exact results show U(1) symmetry substantially suppresses non-stabilizerness in random states, with different leading scaling from entanglement near zero charge density.
