Tunable Chaos in a complex SYK model

We study SYK model with complex fermions with with q fermion interaction and chemical potential turned on. In the large q limit we find that the Lyapunov exponent can be tuned smoothly to zero by changing the chemical potential. The model with flavor symmetry exhibits similar behaviour.
